Are you trying to use radeonfb as a module ? The dmesg seems to indicate
that you have offb taking control of the framebuffer, preventing
radeonfb from loading.

There's no offb->radeonfb handover (the handover mechanism is new and
only used by KMS for now). On those machines, radeonfb should be
built-in.

Cheers,
Ben.
