With ndiswrapper, you should be able to get most wireless cards to work. It's not really that hard to use either. The other day I got a Linksys WMP11 v4 to work in Fedora Core 3. You can get ndiswrapper at
http://ndiswrapper.sourceforge.net/. The site provides good instructions for getting it to work, and the tutorials section here has a few articles on it.
