corrupted glxgears

When using the r600g driver from git mesa (instead of the ati-driver) I get
corrupted 3D pictures as shown by the attachment.
No such issue using r600g from mesa-8.0.2.
All 3D demos are affected as well as google earth and GLC_player 3D apps.

Result of git bisect: 
mesa-c0c979eebc076b95cc8d18a013ce2968fe6311ad is the first bad commit,

Yes, it works without problems with xf86-video-ati driver from git.

I am sorry I can't patch my kernel since I use a precompiled one.

It's not hard to build your own Debian kernel with a patch. It'll be a skill
very useful to you for testing bug fixes.

Even with Option "ColorTiling2D"?

I am not quite sure if ColorTiling2D is really enabled since I am running
kernel 3.3, I understand you need kernel 3.4 to enable 2D tiling properly.

Anyway this is what Xorg.0.log mentions about tiling:
[  2648.738] (**) RADEON(0): Option "ColorTiling2D" "on"
[  2648.739] (II) RADEON(0): KMS Color Tiling: enabled
