Mach64 compile error, kernel flag must be set, but it is

I gave up on Arch and another distro because they aren't playing well with my hardware. Gentoo isn't cooperating either. A Tails live disc boots into the GUI so I know it's possible to get this working. I'm just not sure how. It's been a few years since I've had to do anything like this.

It's a SuperMicro A+ with a H8DAR-i board, dual Opteron 280 dual-cores, onboard Rage XL 8mb which I'm reading should use a Mach64 driver. I'm running 3.12.13 hardened x86_64...
Radeon, r128 modules are built. I read in one place that radeon will pull the Mach64 etc.
Kernel includes ATI Radeon, Rage128, frame buffer including those as well as Mach64, Mach64 generic, Mach64 GX.

Xorg fails (log below) so I'm trying to build the drivers referred to here: http://ubuntuforums.org/showthread.php?t=7200 .

This gives me an error that CONFIG_X86_CMPXCHG must be enabled.
I've checked the .config after make menuconfig to be sure that the CONFIG_X86_CMPXCHG is enabled. It's uncommented and =y. I checked the timestamp to make sure that my latest kernel build with that and the Mach64 options is running. It is. I've checked modules directory in the installer script and it's my latest kernel compile, half an hour ago.

All I want is a simple GUI. Is that too much to ask? Thanks in advance for your help.[/url][/code]

I gave up on the RageXL with Mach64 at least on my ia64 box, and just ran the regular ATI driver. For 2D it's fine... My Rage Pro PCI/AGP cards seemed to work better, but it's been a long time; I wouldn't be surprised if bit rot got the best of them. You shouldn't need to build the mach64 kernel DRM driver if you have it to use the regular 2D driver. I guess for my ia64 box that kernel driver would need to be tweaked...

I do have to mention that at least for ia64 it has indeed bitrot and past certain versions of Xorg it will no longer work. I haven't tried it in a while to see if they fixed it.

Your machine looks like it's getting a mixture of ia32 and x86_64 binaries... hmm...

Which are the ia32 binaries? I thought I'd disabled most unneeded flags in my kernel. I've given up on that driver too. I'm going to use the Xorg driver.

Should I start a new thread for that?

I was able to compile the ATI Radeon and Mach64 drivers from Xorg but no matter what I get "no screens found" now. There is no make.conf anywhere on my system. Xorg -configure yields an error, "Number of created screens does not match number of detected devices. Configuration failed."

"List of video drivers:" (per Xorg -configure)
tdfx, vmware, ati, openchrome, mga, mach64, savage, trident, nv, glint, dummy, r128, nouveau, intel, v41, radeon, vesa, fbdev

Should I try blacklisting everything but mach64, radeon, fbdev, vesa, vmware?

Not sure what is going on there and why you have all those drivers in your system (you shouldn't), but vesa and fbdev should work practically on everything. If this is some sort of server you may consider running X apps remotely (this is a native X feature).

I didn't add any drivers. This is just defaults, plus mach64. Using the Xorg drivers, I'm now stuck at "No screens found".
