Dear Maintainer,
After resuming system after a suspend (to RAM) the display is
corrupted. It is still
possible to see what's going on but everything turns into a highly
unhealthy-looking
(for the display) green-orange flickering mess.
The system is this Apple iMac, see:

I have never gotten this to work in Linux I think, and it's the
only issue that keeps me
from switching to Linux from OS X (sounds works now as of the
Wheezy release).
I observe the same issue on Ubuntu (tried 12.04LTS and 13.04).
You might try a newer kernel or if you are using EFI to boot, try
using the legacy bios option. Unfortunately, macs do just about
everything differently you may need some sort of mac specific quirk to
make it work properly, especially with EFI boot.

Yes, I am using EFI boot. I recall now that I think this used to work
in an old Ubuntu-installation I had, at which point I was still using
legacy bios emulation.
Anyway, thanks for the tip. Would be nice to understand what EFI-
specific quirk that would be needed, if possible, since Debian seems
to boot using EFI by default on EFI-systems as of Wheezy.
Tobias
