Ok, I think I can now reproduce it, and it does not, in fact, appear
to be kernel related. Specifically, doing:

% /usr/lib/xscreensaver/antspotlight & /usr/lib/xscreensaver/atlantis

in a console window (ie. running *two* GL screensavers in parallel)
reliably kills my X server on kernels 2.6.22.17, 2.6.24.4 and 2.6.25-rc9,
with a backtrace much like the ones I posted. So it seems to be an X server
problem that I just happened to encounter for the first time while trying
out 2.6.25-rc6.

Thanks,
Tilman
