Unfortunately the radeon driver heavily depends on reading pll=20
parameters from the firmware ROM which currently doesn't work on macppc=20=

( not sure why - either the driver doesn't like OpenFirmware or it=20

in whatever the console used and won't have acceleration but it should=20=

at least work.

Radeonfb has trouble on R3xx and newer, unfortunately nobody with=20
access to such hardware did any debugging work that I'm aware of so far=20=
