I see the problem. Nouveau for some hardware does a accelerated clearing of the screen before we register the framebuffer. The above patch does fix a real issue so please don't revert it. Can you try this patch.

Hmm, does not seem to work. Any more initialization missing?
Okay. The nouveau driver also uses the pitch as well. It really should be using the pitch field from drm_framebuffer instead of the line_length from fb_fix_screeninfo. This patch is just to make sure this is the issue. I will submit another patch later that uses drm_fb_framebuffer's pitch field. As for the visual unfortunely their is no real mapping between drm and fbdev.
