Try a minimal xorg.conf. Essentially remove everything in it.

I think udev 166-1 should work fine. I had xserver 1.11.1-1 working.

The syscall patch has been picked up by Andrew Morton but it has not yet
been applied to the kernel. Once in the kernel we will need to also
recompile glibc.

That's a general principle for anyone who has been continually upgrading
a much older install for some time. Reduce xorg.conf to practically
nothing. The Xserver now autodetects (via udev) all devices.
