With kernel 2.6.36, wine works just fine on the same system. Does it ring a bell to anyone? Any clue how to investigate this bug? If not, I can start a bisection.
I can also provide any additional data you need for investigation.
It's probably this patch: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdif...
Which exposes a bug in the 3D driver in certain cases. For some reason we get a cb height of 8192 or greater in some cases in the 3D driver. I haven't had time to look into why. You might try r600g for comparison.
Any progress on this? Linus' latest kernel (2.6.37-rc5-git3) still has the problem. And this is a regression, so I don't think you can just ignore it.
Is there a bug opened to track this bug already? I couldn't find one on bugzilla.kernel.org, but maybe I missed it. If there is none, I'll create one.
