I have the lastest from debian unstable.

Well - all the ones I've tried exhibit this behaviour, and none run
forever. Because of the lock ups I've not tested extensively, but
certainly googleearth, blender and amaya cause the problem.

This card worked fine under Windows for gaming, admittedly in a
different system, so conceivably it's hardware, but I doubt it. 

TBH, I don't especially need anything very fast for this machine, so
if the problem isn't easily fixable I might just buy a cheap, somewhat
more recent card.
