It's not a question of whether the card supports mmconfig or not -- the
card can't tell whether a first-256-byte pci config transaction was
initiated through mmconfig, type1, type2, or even a bios call.
I'm just hacking together an implementation based on Ivan's suggestion
to always use type 1 for the first 64 bytes.
