It seems to render itself in different ways for different people. I never see
a hang when it comes out of suspend/standby. Instead, my machine reliably
(everytime and within a few minutes) hangs when I run xscreensaver. It will
also hang if I am moving something accross the screen really
fast............(an xterm window being click and dragged accross the window,
for example).......but this does not everytime.

Perhaps if we had more details of the bug and whats required of the kernel
patch, one of us could help Tim write the kernel patch....
