Do you think this would work, modulo the devilish details?

        1 Link a driver's ieee80211_keys together---put the list head in
          ic->ic_crypto, say.  Modify net80211's set/delete-key methods
          to maintain the ieee80211_keys list.

        2 Modify the drivers' set/delete-key methods to do nothing if
          the power is off.

        3 In the drivers' xxx_newstate() methods, write keys to the
          hardware on a INIT->* transition, using the set-key method.
