Hey there i'm having the same problem here.
I have a Proxim (Agere) orinoco silver card, and a TI PCI-1510 CardBus Controller (PCMIA) on a Dell Inspiron 1100.
When I run ifconfig -a, I get this:

I've tried a lot of different things, none of them have worked. I've asked a lot of people for help, none of them have helped. For the record, I'm currently running SuSE 9.3. I've tried Mandrake 10.1, Mandriva 10,2, Fedora Core 4, KNOPPIX, Linspire (the live version), and a few others. Please help me, as my linux experience is limited too (means i'm a nOOb).
