This is the intended behaviour currently, suspend will fail (and that
patch *definitely* will since you're using KMS) so I made the nouveau
module refuse to suspend.

I've been working on this a bit this week, and have code that *may* work
on your system.  It'll hit git later this week perhaps, there's still a
couple of issues to iron out.

Ben.

compiled a custom kernel and updated DDX driver,
after wake up, the cursor is a transparent square block filled with some colored pixels. screen is shifted up by ~25 pixel and switching screen resolution via gnome-display-properties gives me back an usable cursor and screen.

thank you.

I'm surprised you survived suspend at all actually, only G80 is working properly still at the moment.  Working on it!

Actual state on 9600M GT.
Console testing (KMS enabled, nouveau/linux-2.6 master, rc3, kernel+ddx today updated):
hibernate-ram: working fine! Circa 10 seconds is console extremly slow, but after 10s console working fast

hibernate: it hibernate to hdd, it shudown self, but if is machine power on, LCD is black and system not working. Removing battery and AC power helps. After that system successfully resume from hdd to previous state.

X testing (KMS enabled, no EXAPixmaps)
hibernate-ram: switch to console, suspend, after pressing power try to continue, switch to fbcon, try to switch back X and then screen goes into state from console hibernate (same problem)

X testing (KMS enabled, EXAPixmaps)
can't test, cause now EXAPixmaps rendering one bold line(vertical block on screen circa 3 seconds and it's terrible slow

Thanks.
