I think the module parameter was the deal-breaker. If you can get it
working reliably with runtime switching based on the supplicant's
requested config, that would be great. One problem was that you cannot
require the WPA-enabled firmware, so you'll have to make sure that
anything that does WPA-type stuff is protected by the "wpa_capable" flag
or whatever it was.
