I looked at that yesterday, and sadly I _think_ it's not even possible,
there are some corner cases in it like "no WPA2" that don't seem to be
fully covered in cfg80211/nl80211, at least not with the APIs today and
with current versions of wpa_supplicant.

It might still be doable because things like
WPA_DRIVER_CAPA_KEY_MGMT_WPA2_PSK don't really seem to be used much in
wpa_supplicant, but we'd have to carefully test that I guess.

Also, it depends on the PS3 firmware version whether or not that's
supported.

Then again, arguably wifi without WPA2 is pretty much useless these
days?
