Charles, Jason and I were discussing the idea of changing config so that
it needs:
    struct cfdriver <device><bus>cd;
instead of:
    struct cfdriver <device>cd;

This will allow different probe/attach methods for different busses on
the same device names. I think Jason was working on it and was almost done...

Same deal with the 3com isa ethernet cards; you probe once to find all
the cards.
