Please, somebody who has a reliable way to reproduce this, search for the commit which broke it... use cvs up -D to get a date-based checkout. Given "4.6 works, 4.7 doesn't" and looking at net80211 commits, I would start with a kernel from a checkout dated just before and just after 2010/02/17 (r1.56 of sys/net80211/ieee80211_node.c)..
