Once I'm certain that the problems are not caused by bad hardware or a bad 
configuration on my part I'll try to debug and report the lockups and 
crashes.

I looked around for some free software programs that would calculate an 
average framerate rather than simply showing a FPS counter, but I didn't find 
any.  Something based on crystal-space would be particularly nice.

I also looked at specviewperf, but it takes far too long to run.

Are there any in mesa/progs that stand out?

It crashes without locking the display or even changing the resolution.  This 
one looks easier to debug than the others.
