Yes it seems like X crashes when I switch from the VT console to X
after the resume. My laptop screen is always blank after resume in a
VT console so its a little hard to tell, but I'm pretty sure the
console comes up ok even when X crashes on the switch. However, before
a suspend if I try to attach a gdb before switching from VT to X, gdb
does not finish the attach; it never comes back and the X process
takes all CPU. I've tried that before suspending so I am familar
enough to do it blind after resume; I never did try it after a resume
because gdb doesn't come back to the prompt. Is there something else I
need to do to get the attach to work?

Good point; yes the laptop crashes and needs rebooting; I can't kill
Xorg and I can't alt-ctl-del; I have to power it down. But after
another day or so of testing it seems like the kernel isn't the
problem. With the downgraded xorg packages, and upgraded (2.6.20)
kernel, it seems just as fine as 2.6.17 kernel. And when I upgrade the
xorg packages the intermittent crashing after resume comes back with
either kernel, although it might be worse with 2.6.20 (its hard to be
