'wext' is the future (and cfg80211 after that), so card-specific
interfaces shouldn't be used if at all possible.

I ported the WPA support of the prism54 driver to the 'wext'
wpa_supplicant driver a while ago.  It should be able to exist alongside
the prism54-specific ioctls for WPA.  I was not able to extensively test
it, however, because my card died halfway through.

I believe that patch is already upstream.  Could you test it out?  I
think it's in 2.6.19 and later kernels.

There is also another patch floating around (in desperate need of
testers) that completes the 'wext' support of the prism54 driver.  If
the 'wext' bits of prism54 don't work with wpa_supplicant, we need to
fix that.
