Thanks, I went partially down that path with a different set of instructions that I found... got tangled up and hit a dead-end. These instructions look much better. I am concerned, however, since I found a different post that warned that ndiswrapper would probably not work with an XP driver specifically on core 3. Something to do with the number of stacks available in the kernel and that this could not be changed on FC3. It was stated that this particular problem was remediated in FC4.
At that point, I decided to go the opposite direction... just find a card that is known to work and buy it. I have trolled through a number of the hardware compatibility lists for the various distributions, without getting a clear picture. If there is someone out there that is using a wireless PCMCIA LAN card with Linux that had the drivers either built in or easily accessible, let me know.
Thanks for all your help.
