    Linus,

    Thank you very much! That was it. The following patch made everything
    look good.

    PCMCIA cards now show up. Although I still have yet to get one of mine
    working, but that's because of the card and not the bridge. Now I need
    to start downloading drivers for my card. But at least the kernel now
    sees them!

    Thanks again,

    -- Steve
