radeon driver and wakeup after standby

Hi there,

After wakeup from standby (I use pm-suspend) on my amd e-350 system in some cases the screen will stay off.
The rest of the machine works flawlessly: I can ping the computer, connect via ssh, even enter commands into a shell of the current X-Session (provided I don't mistype )...
Or in other words, the machine does not fail to wakeup but it fails to send a signal to the screen.

Sending it back to sleep and waking it up again works almost always but not always on the first try.

My current kernel is 3.1.9-1-ARCH, but the problem was not introduced by this kernel, it existed before.

Using catalyst or Windows I could not reproduce this error.

I assume this information does not help anyone to fix this problem, so what can I do to produce useful information?
Any useful diagnostic commands I could run the next time I stumble on this issue?
