: I have these two problems:

: - Black screen in the console after wakeup. Console is dead.
: - Shaded screen in X which turns white after a while with nice patterns on it

: OS is still alive. One can login over the network and reboot.

I have the same problem with my machine as well:

drm0: <ATI Rage 128 Mobility MF (AGP)> port 0xcc00-0xccff mem 0xfcffc000-0xfcffffff,0xe8000000-0xebffffff irq 11 at device 0.0 on pci1

It is one reason that suspend/resume for cardbus breaks sometimes
mysteriously...
