It's probably this patch: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=f30df2fad0c901e74ac9a52a488a54c69a373a41 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.
