Subject: [bisected] nouveau failure with 3.9-rc1 and ongoing

Hiya,

Between 3.8 and 3.9-rc1, the following occurs:

Upon boot, when KMS kicks in, I get a blank screen. Keyboard responds 
correctly to "Num Lock" on/off, but machine is unreachable on the network.

Git bisection says:

eb6313add6dddf07ea3e50c4caa33a9c3b2379f1 is the first bad commit

But even though I marked that last bisection kernel good (since it 
didn't cause a black-out), it does have problems, namely that GTK themes 
are reset, and xrandr seems non-functional, inasmuch as my left-ward, 
secondary screen now seems to be treated as being situated to the right. 
No previous kernel in the bisection exercise caused anything of the like.

I'd be happy to try out any and all patches proposed, and as for the 
physical card, this is the relevant part:

02:00.0 VGA compatible controller: NVIDIA Corporation G92 [GeForce 9800 
GT] (rev a2)

Please let me know if there is anything else I can do to help resolve this!

Best regards,

Sune Mølgaard
