Does it happen if you switch to a VT console before suspending? If not,
does X crash when you switch back from VT to X after resume? If so,
could you try to attach a gdb before that?

So, the laptop crashes, not only Xorg, right? If so, what makes you
think it is a Xorg problem, and not something else like the kernel. Even
if the problem occurs less often with xserver 1.1 than 1.3 with the same
kernel, the problem could be in the kernel and occur less often because
of what xserver does above. Hard to say...
