Hm, you really should try talk to the Linux guys. I'm a bit astonished about Attansic's/Atheros' behaviour as even on my Asus driver CD, there is source code for a driver for that chip, IIRC it was even commented so you don't have only magic numbers. If you're interested in that code, I'll search my Asus driver CD and look if the license allows me to publish that files, IIRC it was GPL'd.
