Hi Lubosz

The commit mentioned was part of the big nouveau rework, that landed in the 3.7
kernel tree. Note that the commit has been rebased thus I cannot check why
exactly it's causing issues with your system

>From what I can see is
* With the offending commit, nouveau fails to detect any CRTC (outputs)
connected, thus the issue
* With the commit and "nouveau.reg_debug=0x600" nouveau complains
"nouveau: `0x600' invalid for parameter `reg_debug" and does not load (at least
not mentioned in the log)

Can you try the latest nouveau git or linux 3.7 to establish it this regression
has been fixed or not

Thanks
