I'm guessing it has something to do with the memory map:
-MC_FB_LOCATION (0148)  0x07ff0000
+MC_FB_LOCATION (0148)  0x7fff0000

radeonfb sets it up the same way as the x driver while OF does it differently. 
When the X driver restores the OF values, that is probably what causes the
hang.  Unfortunately, I'm not sure of a good fix.  You might try adjusting the
delays when restoring the memmap regs, or maybe the order in which they are
restored relative to the rest of the registers.
