yuviazzz,
I have no other clue now. I can only guess the "kbd" driver is incompatible with current Xorg version.
I expect to see some messages from xf86OpenConsole(). but they did not show. And it seems did perform the switch_to() function. So I am not sure why/how Xorg pickup keyboard event.
If you want to debug further I suggest create some incorrect configuration value in the kbd configure section. So we can verify the execution code logic did follow assumed path. (It is possible I got wrong idea, I am looking wrong place)
One thing I do know is that "failed to set us as foreground pgrp" no long show in the command version that use "vt1" so the command line option "vt1" did influence the Xorg server. |

Yeah, that's what puzzles me as well.

I don't think that's the reason why the message didn't appear. It didn't because one of the tests used a "Display" entry in the InputDevice section, so a different code path that does not do the tcsetpgrp() call was executed. The one in the else clause. And I still think that Xorg (at least running as root) and the shell that runs startx shouldn't share the same virtual terminal, contrary to what happened in that test.
If fact, going with yuviazzz's information, it seems that the vt argument is actually being ignored, adding to the perception that it is as if code in xf86OpenConsole() didn't run:

yes & yes. |

This is why I think giving "wrong" value in configuration is a way to debug. Because otherwise we need to build the code with debug information in order to trace execution path. Now we are just guessing base on the code we see.
I read somewhere on Internet that suggest X should need to work with controlling tty. that is the reason I suggest use "vt1" as where the startx was used.
Without set in front of the screen it is very hard to guess what exactly happening, there are a lot more information required in order to really determine what was the execution environment. For example using the "ps ..." command you suggested to verify if we did not somehow missing the required argument may be due to for example ~/.xinitrc or something.
examine /proc/<pid of Xorg> would be another place to check. and there we can also check if the control tty is set correctly. There just too many thing to check and over this forum post is very inefficient. |

yuviazzz, could you post the output of Xorg -help? I want to see if at least xf86UseMsg() from hw/xfree86/os-support/linux/lnx_init.c is called...

yuviazzz,
There are two parts to the evdev driver
You need the kernel part, not the Xorg part,
In xorg.conf I have
| Code: | Section "InputDevice"
Identifier "Keyboard1"
Driver "kbd"
Option "AutoRepeat" "500 30"
# Specify which keyboard LEDs can be user-controlled (eg, with xset(1))
# Option "Xleds" "1 2 3"
# Option "LeftAlt" "Meta"
# Option "RightAlt" "ModeShift"
# To customise the XKB settings to suit your keyboard, modify the
# lines below (which are the defaults). For example, for a non-U.S.
# keyboard, you will probably want to use:
# Option "XkbModel" "pc105"
# If you have a US Microsoft Natural keyboard, you can use:
# Option "XkbModel" "microsoft"
#
# Then to change the language, change the Layout setting.
# For example, a german layout can be obtained with:
# Option "XkbLayout" "de"
# or:
# Option "XkbLayout" "de"
# Option "XkbVariant" "nodeadkeys"
#
# If you'd like to switch the positions of your capslock and
# control keys, use:
# Option "XkbOptions" "ctrl:swapcaps"
# These are the default XKB settings for Xorg
# Option "XkbRules" "xorg"
# Option "XkbModel" "pc105"
# Option "XkbLayout" "us"
# Option "XkbVariant" ""
# Option "XkbDisable"
Option "xkblayout" "gb"
# comment out the next line if you don't have a dvorak keyboard
Option "xkbvariant" "dvorak"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
# why "pc102"
Option "XkbOptions" "ctrl:swapcaps"
EndSection |
The whole file will be there for a day or so.

with:
| Code: | Section "InputDevice"
Identifier "Keyboard0"
Driver "evdev"
Option "Device" "/dev/input/event5"
Option "AutoRepeat" "500 30"
Option "xkblayout" "se"
Option "XkbRules" "xorg"
Option "XkbModel" "pc105"
Option "XkbOptions" "ctrl:nocaps"
Option "GrabDevice" "true"
EndSection |
in xorg.conf and server flag to disable AutoAddDevices, i can get keyboard working like this with evdev.
replace "evdev" with "kbd" and remove GrabDevice option, i see it complaining it cant grab keyboard in tty, and keyboard does not work in X. 
with GrabDevice option removed and driver still set to "evdev", keyboard works in X but also in tty, letting me ctrl+c out of X. very annoying  |

"small" system changes... well, i no longer need GrabDevice option with evdev, and i can now actually "use the keyboard" with kbd driver (input i get is not correct at all, full of interference, only with device specified!) so im satisfied  |

| Please give us the long story instead, for the benefit of anyone else who has this problem. What was wrong with your /dev, how did you determine that, and what did you do to fix it? |

My guess, You miss /dev/tty0?  |

I knew it. I should'vs capture it last time when I ask for the /dev/tty listing. I had a feeling then something was missing in the static configuration. But I was too much of reading the source code, just miss the big picture.
I think also the disable AutoAddDevices helped. Should have read the man page.
| man xorg.conf(5) INPUTDEVICE SECTION wrote: | | The config file may have multiple InputDevice sections. Recent X servers employ HAL or udev backends for input device enumeration and input hotplugging. It is usually not necessary to provide InputDevice sections in the xorg.conf if hotplugging is in use (i.e. AutoAddDevices is enabled). If hotplugging is enabled, InputDevice sections using the mouse, kbd and vmmouse driver will be ignored. |

yuviazzz is using a static /dev setup, so x11-drivers/xf86-input-keyboard is the only option here. And only the last version that still had the code for Linux. |
Late to the party, but I wanted to mention that this is not exactly correct.
You can use evdev too, but you need to use libudev-zero with it.
libudev-zero is code unrelated to udev and systemd.
It's a couple of functions that are needed by some programs and libs, like evdev.
I have an ebuild for libudev-zero in my overlay.
I have tested evdev running like this on my static /dev machine, and it worked with no issue.

I want to say that xf86-input-evdev + libudev-zero does look IMO like a better alternative for X11 + static /dev users than xf86-input-keyboard + xf86-input-mouse. At least while libudev-zero is maintained.
evdev_drv.so uses only these functions from libudev:
| Code: | U udev_device_get_devpath@LIBUDEV_183
U udev_device_new_from_devnum@LIBUDEV_183
U udev_device_unref@LIBUDEV_183
U udev_new@LIBUDEV_183
U udev_unref@LIBUDEV_183 |
All of them are implemented in libudev-zero's replacement library, and all appear to do actual work, i. e. they are not just stubs.
This of course puts the system in unsupported territory —libudev-zero is not, and probably will not be (likely conflicts with sys-apps/systemd-utils[udev]), in Gentoo's official repository—, but so does using old, unmaintained (for Linux) X11 input drivers
