I just tried the new ATI driver and I didnt have any success resuming 
from a suspend to RAM. I tried it twice and the result was a lock up 
after resuming. All I see after resume is "inu" on the screen.

X: xorg (6.8.2)
Linux Kernel: 2.6.13
PM: ACPI
Machine: T42p

Any ideas? I would love to get ACPI suspend/resume (to memory) working 
with DRI support.

The open-source radeon driver works flawlessly as far ass the 
suspend/resume is concerned - but without DRI.

Any help/hints will be much appreciated.
