>Description:
The Intel PRO/wireless 2100 can't associate with an access point on FreeBSD 8.  ifconfig wlan0 list scan shows nearby access points, including the correct one.  But wpa_supplicant never manages to associate, but retries every ten seconds.

ifconfig wlan0
wlan0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
 	ether 00:0c:f1:4e:b1:ac
 	media: IEEE 802.11 Wireless Ethernet autoselect (autoselect)
 	status: no carrier

>How-To-Repeat:
rc.conf:
wlans_ipw0="wlan0"
ifconfig_wlan0="WPA DHCP"

loader.conf:
legal.intel_ipw.license_ack=1
if_ipw_load="YES"

wpa_supplicant.conf (copied from another 8-stable system with working Atheros 
hardware):
network={
   ssid="myssid"
   psk="notmyrealpsk"
}

# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf
