I have 2 Ralink cards (rt2500) working perfectly with Dapper. The chip
manufacturer has started an open source project with drivers and a
configuration utility (It's great to see WPA working within 4 seconds).

I would start looking for a USB-wireless card based on that chip (as
far as i remember the USB-variant from Surecom (which however is using
other chipsets as well) costed about 19€)
