[Bug 557104] [NEW] nouveau fails to display anything on PPC

[Aurelien Naldi]

Public bug reported:

Unexpected good news for me: the nouveau kernel module was enabled on PPC in 2.6.32-19.
Unfortunately, the display now turns off early in boot (before X launches) and the screens complains about the lack of input then about input being out of range.

I tried without success to remove the "splash" boot option or to force the resolution with video=1280x1024
Using the previous kernel and the nv X driver, I have a (very slow) display and a text console
Using the previous kernel and the nouveau X driver I have a messed-up X display (800x600 and colors scrumbled) but a working text console.
Using the new kernel I don't even have a text console.
I didn't yet try blacklisting the nouveau module, I'd much rather find a way to make it work!

Is it a better way to force the video mode or alternative kernel options
to try ?
