If your driver doesn't support returning the WPA IE in the scan results,
it's certainly not going to work with WPA and wpa_supplicant.  Smells
like a driver problem.

What driver are you using?  Does that driver really support WPA?  What
hardware version is your card?  Is it prism or prism2 based?  What
firmware version are you using?  Linksys has a long history of calling
something the same product name but switching out chipsets; you may not
have the card you think you do.

Do an lsmod and lets see what driver the kernel is binding to your card.
If you're using 'orinoco' drivers, they don't do WPA.  You might try
blacklisting the orinoco ones and using the 'hostap' driver instead.
