I hope it won't. The brightness adjustment is not optimal (BenH said
that it might even damage the hardware) and it really belongs into
rivafb, where it has already been merged, has the correct brightness
values and gives you fullscreen mol, although that currently has some
problems ;) Offb is limited to 8bpp, btw.
Rivafb works quiet well on NV17 now, it still has problems on NV30
