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.
