rt2x00 is a project to support Ralink RT2400 and RT2500 chipset for 802.11b and g. The really interesting bit is that Ralink release their Linux driver under GPL, unlike most of the other manufacturers. So I'd encourage anyone willing to get a 802.11g card to run on Linux to get one using RT2500.

I personaly haven't tested it, but I put that on my list.
