xorg hang after resume

[Doron Fediuk]

Thanks Colin.
I managed to ssh my machine after resume (while it hangs).
I tried to stop the xdm service. But it failed.
So I checked with top: X was using 97-99% cpu.
I managed to kill most of kde's processes. 
I tried to kill X, but even kill -9 wouldn't work ! (first
time I see a process which won't go down for kill -9).
Eventually I had to reboot (better then cold-start..).

As for vbetool, I know it helps, but mostly for other HW.
So far everything worked smoothly without it, and I prefer to
use it only as a last resort (and not sure it'll help...).

Any idea how to resolve this ?
Thanks !
Doron
