But I couldn't tell you which cards they're in. Other than that I think the NDIS wrapper at www.linuxant.com works with some G cards (I'm using it for a Centrino b card) - it costs $20. There is also a GPL NDIS wrapper at http://ndiswrapper.sourceforge.net/ which I haven't had a play with yet (it's quite new, and came out after I'd bought the linuxant wrapper).
I use the Ndiswrapper with my IBM R40 Centrino laptop. It's worth bearing in mind that although the project is GPLed, it still uses the Windows .sys and .inf driver files to communicate, so your system will not be entirely "Free". There's a reasonably active mailing list too. HTH, Tony
