xorg.conf
Playing with colorTiling was unhelpful. Playing with resolution changes
nothing. It simply doesn't work if i set DefaultDepth to 16 (for UMS).
Disabling PAT support via nopat kernel option changes nothing.

Glxgears in UMS was working (with same userspace) up to kernel
commit 6d6b89bd2e316b78d668f761d380837b81fa71ef
Merge: 13dda80 2507c05
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date: Tue Mar 2 07:55:08 2010 -0800
in mainline. I halted git-bisect because original good/bad pair was not about
this bug, i wrongly assumed new kernel was unable to "fix" bug 22576.
I can re-run git-bisect, but it will take time ... anyone want to beat me on
this?

Sorry, original dmesg was splitted by syslog, it seems. Here is more complete
version.
