rtk(4) really has MI framework and it works on alpha, arc, i386, macppc
and dreamcast. I guess iha(4) (Initio INIC-940) is also one of the low-end,
but it also works on all machines which have PCI.
IMHO, all PCI drivers _should_ work on all architectures
even if there is no user of it on such machines :-)

inb() and inw() can easily be relaced by bus_space(9), but
all use of vtophys() should be re-written to use bus_dma(9) framework.
I guess it is a bit boring work, but it will help someone in future ;-)
