Comment 58 for bug 1043518

Just to correct my post #55, since on the logs nouveaufb looks like it is loading fine for you then you can use the fbdev driver with that. All you need to do is create an xorg.conf that specifies fbdev (don't use the nomodeset parameter). If you still get 8 bit graphics then you need to increase the colour depth at the yaboot prompt. It is very easy, but I would try setting up an xorg.conf with nouveau first.
