xorg.conf

I did a fresh install of rawhide today.  KMS for nouveau works, but Xorg defaults to vesa for the display driver.  This results in display corruption.  When I create an xorg.conf and tell Xorg to load nouveau, I get a kernel panic when Xorg starts and Xorg just freezes on a black screen.

So, two problems here:
1. Xorg should be defaulting to nouveau
2. kernel shouldn't crash
