UUgh!

	No wonder the wireless cards were being excessed for $14. You hit the nail on
the head Thomas:

[16:02 supersff:/home/david] # wpa_supplicant -B -Dwext -i wlan0 -c
/etc/wpa_supplicant.conf -dd
Initializing interface 'wlan0' conf '/etc/wpa_supplicant.conf' driver 'wext'
ctrl_interface 'N/A' bridge 'N/A'
Configuration file '/etc/wpa_supplicant.conf' -> '/etc/wpa_supplicant.conf'
Reading configuration file '/etc/wpa_supplicant.conf'
ctrl_interface='DIR=/var/run/wpa_supplicant GROUP=wheel'
eapol_version=1
ap_scan=1
fast_reauth=1
Line: 6 - start of a new network block
<snip>
WEXT: Operstate: linkmode=1, operstate=5
Own MAC address: 00:13:49:54:2b:c9
wpa_driver_wext_set_wpa
Driver does not support WPA.
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

** I updated the wiki to reflect this fact.

	Well, since it works flawlessly under XP and I have the install CD, looks like
I'll have to put my dislike of using the windows driver aside and run
ndiswrapper :-(
