More on the previous post. It appears that the updated Mesa does fix this problem, but other programs like warzone 2100 and wine are built against mesa 1.4 libraries and they crash the whole system. The updated radeon drivers don't seem to have any noticeable effect. In order to implement this fix with the 1.6 base, just about every Mesa linked 3D program would also need updating. I doubt this will ever happen, but the fix mentioned above can be applied to the 1.4.0 branch. The details of the official patch are here:

We just need to backport it.
