I see a similar message using a nVIDIA card with nouveau:

fb: conflicting fb hw usage nouveaufb vs OFfb NVDA,Displ - removing
generic driver

It doesn't seem to interfere with successful loading of the nouveau
driver. (I'm guessing this message corresponds to the moment during
boot when the console display briefly becomes garbage before
flickering a bit and settling back down with the newly loaded driver.)

I don't have any graphics listed in /etc/modules which I'm aware of:


I did, however, have to edit yaboot.conf to prevent nvidiafb being
loaded else nouveau wouldn't load at all.
