radeonfb.c fixes

[David Mosberger]

I thought we had fixed this already, but now that I tried radeonfb
again, it didn't work (on ia64 linux).  Patch below fixes the problem
(OK, I don't really know if the fbdev output looks correct, as I'm
working remotely today, but at least it gets the machines booting
again and in the past, this was the only problem).
