Comment 2 for bug 128765

As an option, you can always use ndiswrapper: http://ndiswrapper.sourceforge.net/
with the drivers from: http://www.atheros.cz/

I used the AR5008 XP 32 bit drivers for my toshiba U305 and they works, provided that you never try to load the madwifi drivers (i.e., you have to blacklist them by adding "blacklist ath_pci" and "blacklist ath_hal" in /etc/modprobe.d/blacklist).
