I'm happy for you to do that if you are interested.
The way I read it, you'd need to backport "cfg80211: add PM hooks" (which is trivial), then either backport all the cfg80211 scanning (yuk!) or add something to cfg80211_ops to notify mac80211 of suspend/resume events. Given the later, then you'll need to reformulate our aging changes around bss->last_update.
Of course, YMMV...maybe you see something I missed! :-)
