That's a classic gpu lockup.
Those are hard to debug. You can try upgrading to latest drivers
(dri/ddx/drm). You say "most" opengl programs - some specific ones which
run forever or crash fast? The 8500 in particular is a somewhat delicate
card (as opposed to 9000/9200), as it needs some driver workarounds for
hw bugs which are likely not quite done right in the driver under some
circumstances (though that shouldn't affect "simple" apps like quake3).
HW failure (either insufficient cooling or just bad hardware) is another
possibility (try other drivers / OS to rule it out).
