Hi!
After syncing git tree to bd381934bf13ccb1af2813ae26c6fe00ec85d254
I've experienced pixel color corruption in Xorg.
Some of pixels (not all) have abnormal colors seen on images like this:
Loading Image...
[1.5M]
(you won't see any problem until you run -rc3+ kernel).
I've bisected it[2] and found offending commit[1].
My hardware is HP Compaq 2510p laptop:
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
Do you need more info?
Thanks!

068143d38804825d59d951a192cfadd2e22f457d is the first bad commit
commit 068143d38804825d59d951a192cfadd2e22f457d
Date: Mon Oct 5 09:58:02 2009 +1000
drm/fb: add setcmap and fix 8-bit support.
This adds support for the setcmap api and fixes the 8bpp
support at least on radeon hardware. It adds a new load_lut
hook which can be called once the color map is setup.
