Is possible to use EAP-FAST directly from windows without using ACU??? If not is there list of wireless cards supported by ACU???
afaik you need some special driver for the EAP-FAST authentication.
Atheros Chipsets usually have drivers with an EAP-FAST option e.g. in some orinoco gold cards. Also the Funk Odyssey Client is EAP-FAST capeable.

I hope that helps a bit.
