I saw bwfm0: in /var/log/messages, from memory, similar to the ones listed.
One error. autoconfiguration error: NVRAM file not available.
The CHIPACTIVE line is missng.

ifconfig does not show bwfm0, only genet0 and lo0.

I managed to get a wired connection (across the room at chin height...)
Networking is up. ntp set the date correctly. DNS works. I can ssh into 
the system.

It has been 5 or 6 years since I ran BSD. I used Berkeley BSD and FreeBSD.

How do I get wifi started? I can start wpa_supplicant and I have a 
network block in /etc/wpa_supplicant.

network={
  ssid="xxxx"
  psk="yyyy"
}

service wpa_supplicant onestatus shows it is running
