I had an Orinico wireless card that worked in my Lombard with their drivers under OS 9. YOu can go to their homepage and see what cards they have that work with their Mac drivers. Problem was, it wouldn't work with OS X. I got a Microsoft MN-720 cheap here in the Marketplace, and Panther recognized it as an airport card without any drivers or anything. Worked great, and is wireless-g capable. Jaguar, on the other hand, did not recognize it.
