Finishing a complete new install of 8-stable on a Thinkpad T42.  This 
model came with the Intel PRO/wireless 2100.

Despite being 802.11b only, the 2100 with the latest firmware does
WPA2 on Windows XP.

So far, it has almost but not quite been able to connect using WPA on 

ifconfig_wlan0="WPA DHCP"


wpa_supplicant.conf (copied from another system which has Atheros 
wireless and works fine):

ifconfig wlan0 scan sees all the nearby access points, including mine.
wpa_supplicant can't quite attach, but doesn't give up trying.

ifconfig wlan0

That repeats at ten-second intervals.
