Yeah.. It look like linksys released a new one for the v.1 series that supports WPA.. however, the release docs for the v.2 stuff sucks.. I am not sure if the new drivers support WPA or not. I would try the new drivers and see.
I know for a fact that they will not support WPA2 at all.. So you will be stuck with WPA-PSK. Which isnt a bad thing. I am not sure why you would want to run AES on a home network...
