Failed to load module "Radeon"

Hi, I have recently upgraded my X.org to 7.0 and since then my X wouldn't start. Seemed like I have to update the driver for my mobility radeon 9200. So I did and I got an error saying unrecognized chipset after the upgrade. Reading around the forums, I found out that ATI no longer support my graphics card and so I have to look for open source alternatives.

I added x11-base/x11-drm ~86 to /etc/portage/package.keywods
and added x11-base/x11-drm video_cards_radeon to /etc/portage/packages.use

Did an
emerge x11-xorg

Now when I try starting X with "radeon" as my driver I get failed to load driver "Radeon"

I've never played with radeon cards but 2 thoughts spring to mind, in your /etc/make.conf file have you added the appropriate driver to the
VIDEO_CARDS="radeon"
and then emerged X11?

and also have you modprobed the related radeon modules into the kernel?

I had this the problem for quite some time...

check this out http://gentoo-wiki.com/HOWTO_DRI_with_ATi_Open-Source_Drivers

Make sure you "make clean" your kernel, although I am not sure why you are not using 2.6.18.2 the latest stable. Unless there is a *GOOD* reason to do so I would suggest strongly that you ungrade to this and *keep* 2.6.10 as a stable kernel.

I would suggest removing with rm -R your /lib/modules/2.6.10 *if* you are going to use the same kernel which I would NOT suggest. You should keep this as a backup.

You have the choice of using the drm from the kernel or from xorg. You are currently *mixing* both. If you previously use the one from the kernel it will try and use that one!? I have no idea why. It is not your fault.

After you have upgraded I suggest you re-emerge x11-base/x11-drm again.

You should end up with something like this...

Thanks for the reply. I'm going to try upgrading the kernal and see how it goes and let you guys know.
thanx again

I've emerged the lastest gentoo-sources and did genkernel, setup grub to boot the new kernel and rebooted.
Got the error message "block device is unspecified or not detected".
I am 100% sure I have the same parameter as the the other 2.6.10 kernel, ( except ofcause the initram and kernel image ).
I looked around and I found that there is a bug with genkernel and I need to put udev at the end of the kernel line, ( similar to my other box ). Reboot, doesn't work. Run grub again, still giving the same error message.

Think I might do a manual kernel build instead of using genkernel and see what happens.

Okay got it booting up by using the manual build of the kernel.

Tried using the kernel radeon driver

Mmm... From the link it says I could choose to either use the kernel driver or the separate DRM module. So I treid the kernel module first, that didn't work so I then emerge the drm separately. But forgot to take out the kernel version. I've done that now.

I already have in my /etc/modules.autoload.d/kernel-2.6
