It's possible that your VGA card is so broken that it only use the low-order bits of addresses and use the high addresses as flags, for example to access a "bug endian" aperture :) That would suck as it would mean you actually have address aliasing going on on the bus, possiby causing weird conflicts. >I'm curious about PCIBIOS_MIN_MEM...
