PCI 802.11g client cards

I have about 7 client PCs (mostly SuSE linux 9.2) to network (again, after a fire), and I want to do it wirelessly this time. I'm used to having a laptop client, but not desktop clients. I have an 802.11g access point. I'm looking for suggestions -- PCI cards, PCMCIA adapters and PCMCIA cards, WRT54G in client mode, others? I don't see typical Linksys PCI cards indicated as being supported. TIA, Ed A.
