Well, Ill test tonight....
I have a PCMCIA one and Ive theoretically tested it but without connecting when i was bored on a train!!!

It seems like its working but Id hate for you to buy it and then it not work...

From the HD install I can guarantee it works....with a Netgear WA311
Im also using knoppix as a router on a HDinstall with a WG311 and abolute nightmare card under linux. Using linuxant driver installer it works great under knoppix HD install.....

I didn't actually try MADwifi etc... but. its a bit more complex and IMHO not worth the hassle in your case when you can do a HD install.
