digicam picture of both monitors

After resuming a previous (via pm-suspend) suspended system 
the second monitor only shows a garbled picture.
Running xrandr to switch resolution seems to work, but
the picture still ist truncated.
This is a kms/multihead configuration.

Used software:
  Kernel-2.6.35-rc5
  latest xf86-video-ati from git
  latest libdrm from git
  latest mesa from git

Does the other monitor work properly if you turn it off and then re-enable it
with xrandr (e.g., --off, followed by --auto)?

Does doing a VT switch before suspend help?

No / No.

It even doesn't seem to work after a warm reboot.
I only get a test picture (as if there was no 
connection between monitor and graphic card)
when the bios boots up.

I had to hard reset the computer 
to get a working second monitor again.

Does the second monitor enable properly if you cold boot without it attached
and then attach it after X has started?

Appendix:
If i run 'xrandr --output DVI-1 --off' followed by
'xrandr --output DVI-1 --auto' the second monitor switches off
and then on again (garbled screen).

Now if i run 'xrandr --output DVI-0 --auto' (happend accidentally first time),
monitor one switches to off and the second monitor shows
a correct piture again. Huh?! 
Running 'xrandr --output DVI-0 --auto' afterwards makes
monitor one work and monitor two have a garbled picture again.

Will now try that cold boot thing.

I think Yes.
I have to run 'xrandr --output DVI-1 --auto' to 
get my desktop back, though.

Update:
Enabling "Repost Video On S3 Resume" in BIOS seems
to help a lot. I've send my computer into sleepmode
for a couple of times now and the second monitor has 
always been working fine after resuming.

I actually dunno what this BIOS option does,
but it seems to be a solution.
