The "Mac" cards don't have an x86 BIOS in ROM, they have an Open
Firmware instead, we need to fix proper detection of that, but that's
something I can try to do. I didn't finish merging it yet, I've been
quite busy with other drivers this week, radeonfb is on my todolist
for this week-end.

Yup (Note: the need for EDID in low RAM happened with x86 configs, on Macs,
I get it via the Open Firmware device tree).

Ben.
