dmesg without drm.debug

I'm using nouveau from the git kernel to drive the GeForce 9400M, the only
graphics adapter in my MacbookPro 5,5.

My Dell U2312HM monitor (1920x1080@60, attached via DisplayPort -> DisplayPort
cable) won't show a static picture, moving pictures make the flickering even
worse. The problem still stands in the highest pstate level and with only the
DisplayPort as active output. I also tried a DisplayPort -> VGA adapter and got
the same result.

Included two dmesg:

1) Without drm.debug
2) With drm.debug=0xf, flooded
