Agreed, for the most part.  I use an 8500 and 9200 at work and at home.  
I regularly update my Mesa tree and build new version of the r200 
driver.  The only problems I've experienced is if I leave xscreensaver 
up and running all night, randomly choosing from the OpenGL 
screensavers...  I'll sometimes (once a week, maybe) find X locked 
solid, and only a reboot will get it working again.  The XiG drivers do 
this as well, the only difference being that I am able to just kill the 
GL screensavers that are locked up and get my display back :-)

I think perhaps the biggest culprit for this problem with the Mesa 
drivers is that I run a MergedFB desktop at 2560x1024, and each screen 
is supposed to display it's own screensaver, but that's just speculation.
