Ok, it really does look like incomplete testing. :(

Please compile the kernel w/:

IEEE80211_DEBUG
ATH_DEBUG
AH_DEBUG
ATH_DIAGAPI

... I think that should be enough to get all the good debugging that you need.

Then you can use wlandebug to log what's going on when net80211 goes through
states:

wlandebug -i wlan0 +assoc +state +scan +mlme

Then run wpa_supplicant and see what happens.

Meanwhile I'll go update my -HEAD laptop again and go setup 13.1-RELEASE
somewhere with an ath(4) NIC and see what happens. The only thing that's really
ar9285 specific is 1x1 stream 11n + STBC; everything else should be the same on
all 2GHz supported ath(4) NICs.
