Ah, now I see that it is PPC... With card from Matrox? 

If you'll look at matroxfb_read_pins(), you'll find that driver reads framebuffer
base address and enables BIOS at that address - it is solution recommended
by Matrox if BIOS is disabled on device. You should probably instrument
parse_bios() to make sure that it finds what one would expect. Region is
uncacheable, so there should be no problem on CPU side, and on hardware side
mga chips are designed to have all four memory regions overlapped, and their
behavior is specced for such configurations.

But if your card comes with firmware from IBM, you'll have to ask IBM. Unless
their firmwares conform to memory layout Matrox itself uses.
