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,
