No can do. The Maple platform can't generate any PCI memory access below 
0x8000.0000. So it can't access  the VGA buffer. I have removed all 
these accesses from being generated by the emulator. (all other acceses 
to the card, including  PCI I/O accesses  to the VGA registers remain 
though).
I am looking at the radeon driver. Maybe it is confused as it thinks it 
is running on an OF based machine while at the same time locates a x86 
VGA BIOS.
