Do we have 802.11n cards and driver for Linux?

So I'm poking around Slashdot (don't we all?). And I read that "Atheros Releases Free Linux Driver For Its 802.11n Devices". Cool, finally I can get 802.11n for my home setup. So I bounce over the link provided Madwifi announcement (the Slashdot comments have the usually, rants, raves, gibberish and a few comments with useful information) and find that they even have a list with cards that are supported by the drivers (though it was the 5003 802.11n chip, not the chips mentioned, odd). Anyway the more important thing is that we now have various 802.11n boards for Linux.
