Does this patch help? You might also try it in combination with this patch: http://lists.freedesktop.org/archives/mesa-dev/2013-February/035347.html
Tried proposed patch and the 5 patches from the link (the link and the 4 others) and still the same corruption.
However, I noticed the errors seam to have gone with latest mesa from git (no link with the patches, tested with and without them). I ran steam and RendererFeatTest64 and no error appeared in dmesg anymore. What about you Jakob?
