I'll rebuild soon with this option set, since I'm running 
GENERIC-NODEBUG right now.

I do this in wpa_supplicant.conf:

   network={
     ssid="Casa di Mau"
     scan_ssid=0
     psk="<foobar>"
     priority=5
     bssid_ignore=f0:9f:c2:03:c7:51 f0:9f:c2:ad:40:6e 98:ba:5f:d7:71:b2
     frequency=5240
   }

And in rc.conf:
   ifconfig_wlan0="WPA DHCP country NO regdomain ETSI chanlist 36-100"

Attached dmesg from boot right now. The interface did not come up 
properly  until I did a "service netif restart wlan0" (not included in 
the dmesg).

Gotta run now, can collect more debug info later.. Hope this helps, though!
