Yes, the DBAu1500 board does not have CardBus support. We want to support
802.11A/G, so at the moment I have a 3.3V PCI card with a Texas Instruments
1510 CardBus bridge. A lot of modern wireless cards are CardBus-only, so that's
why we have decided to incorporate the TI bridge into our boards.

If someone out there has some notes or tips concerning getting PCMCIA working
under this architecture, I would greatly appreciate the information.

Take care, and thanks again!
