W520-4276CTO-NVC3 dmesg 3.8.0-rc1 suspend/resumce cycle screen garbage

Tested NVC3 3.7.1 openSUSE kernel and nouveau 3.8.0-rc1 as of 2013-01-03. Both
show same screen distortion (snowy background, button background and window
border ok) on gdm when resuming. Though the system is "usable" load wise and
doesn't lock-up.

Am I still in the scope of this bug with the following endlessly repeating
errors on resume? (Which will go away if killing X.)
