Hello etchosts,
i'm sure that the card is based on rt2500 chipset, u need to get the drivers for that chipset, i use debian so i know the drivers are in repositories, but check this page
rt2x00 Project is the main page of the project who develop linux drivers based on ralink chipsets: rt2400, rt2500, rt2570, rt61 and rt73.
Another post here on LQ about rt2500 with mandriva

Hope it helps. Cheers
