I was hit with the same thing.  In current CURRENT, you have to create 
these wlan devices.  One way is to put lines something like this into 
rc.conf:

wlans_iwn0="wlan0"
ifconfig_wlan0="ssid crazylegs DHCP"

To be honest, I am still at a loss as to how I managed to figure this 
out - I guess I got luckier with the googles.  "man ifconfig" helps, but 
you have to read the right parts.  "vi /etc/default/rc.conf" also 
provided some clues.
