It is. See src/sys/net80211/ieee80211.c:1.16.
AFAIK, the problem is that there are some interoperability problems
when you have both WME + WPA enabled. Disable one of them should be a
possible workaround. I believe that Sam has some fixes in his queue;
however, those fixes were not yet ready for the forthcoming 6-RELEASE.

That's what I observed around here: sometimes it takes wpa_supplicant
looping multiple times before negotiated to the AP(w/ or w/o hidden SSID).

Apart from multiple regotiation sometimes, scan_ssid=1 works for me.
Have you tried to set the IP manually(no dhclient) after ath0 was
associated with the AP?
