Ah, no, that's a different question, sorry.  WPA2 requires different
hardware than plain WPA.  WPA2-capable cards are required to support
CCMP/AES encryption, which requires either updates silicon, or a
softmac-like driver coupled with really shallow silicon.

So it's not a given that any card which supports WPA can actually
support WPA2.  You'll need to find out if the card supports WPA2 first
through either product marketing information, or possibly using it on
Windows and trying WPA2.
