And both nvidiafb and vga16fb are known make Nouveau misbehave:
nvidiafb because it messes up the card state, and vga16fb because it
does not do the fb driver hand-over, AFAIK.

Relevant or not, I'd like to advertise our new troubleshooting page:
http://nouveau.freedesktop.org/wiki/TroubleShooting

I'm also adding the CCs that were dropped earlier.

Was the original question in this thread about nvidiafb or Nouveau?
