I committed a couple changes to machfb which may help here, please try
a -current kernel from yesterday or later. It should:
- no longer freak out about hardware not set up by OF
- avoid unnecessary video mode changes
- not try to program video modes above 1280x1024 ( unless set up by
  firmware ) in order to avoid a known bug in machfb

I tested this on a beige G3's onboard Rage II and a Sun Ultra 60 with a
PGX64, aka Rage XL.

have fun
