Sorry, I was in a bit of a hurry when I worte those replies, if you open a terminal then type "su" without the quotes (it will ask you for the root password) then type "lsmod" you will be presented with a list of the current modules (drivers) that are being used. I've a feeling it will be ndiswrapper thats driving your wi-fi, but feel free to post the list here if you can't identify it.
