When I said "that crap" I was talking about those interfaces which I
-hope- are deprecated :-)

I suspect we never really sorted out the issue of DMA mapping for old
legacy ISA stuff... pci_map_* should work to some extent, though you
have to pass it the ISA bridge pci_dev.

Maybe it's time for somebody to start exposing a -proper- abstraction
accross all platforms for that :-)
