Thanks for taking time to explain.
Turns out PEBKAC. I had this offending line burried in rc.conf
create_args_wlan0="country DE regdomain FCC4"
According to regdomain(5) <!-- FCC4 is 2.4GHz FCC w/ Public Safety Band (PSB)
-->
So I was forcing my card to do 2.4Ghz it seems, removed it - everything worked
like charm. I can see and connect to 5GHz 11a aps.
