I've read that the NWP11B PCMCIA Wireless Card uses the Reltek RTL8139 Chipset which has been reported as working out of the box with pervious versions of OS X. I'm using 10.5.6 on a Compaq 8510p.

System profiler lists the following information for the card.

Function: Ethernet Controller
Vendor: Unknown
Type: CardBus
Vendor ID: 4332
Device ID: 33152

Any help?
