Did you update anything besides the kernel between 2.6.38 and 2.6.38.1 (mesa of
xf86-video-ati)?  If the same userspace components (mesa, xf86-video-ati) work
on 2.6.38 and become garbled on 2.6.38.1, can you bisect between 2.6.38 and
2.6.38.1 and see which commit caused the problem?  If you updated the userspace
components as well, this is probably a duplicate of bug 33929.
