This MAC address is not reserved for any vendor, but MAC addresses
starting with 00:03:7f belong to Atheros.  I think it indicates the
Atheros card uses several virtual interfaces, one of which is what you
are seeing.

I suggest that you check in the monitor mode that there are indeed
beacons sent with this MAC address.  Maybe they are not.  It's quite
possible.  MadWifi has an option to disable beacons for some virtual
APs.

Maybe mac80211 decided to do a passive scan, perhaps due to your country
regulations?

It's quite possible that b43 will associate if you set the ESSID
correctly.  Maybe you'll need to set "ap" with iwconfig as well.
