OpenSUSE Wireless :: No Automatic Connection With Little Edimax?

I have just upgraded from 11.2 to 11.3 my Dell Inspiron 5100 with LAN adapter Edimax Ew-7711utn. It was working fine under 11.2, without using Network Manager. The old RT2870 driver was loaded and wpa_supplicant started at boot time. But it does not connect any more automatically with 11.3. The nl80211 almost universal driver seems to be missing, wpa_supplicant is not launched during the boot process, and no connection to the AP is therefore made. I have tried quickly NetworkManager but it is of no help in this case. There is still a long way to go to make it a reliable clever tool. So, back to the ifup method, I can only connect manually with this small script :

#!/bin/sh
echo "Starting mywifi "
/usr/sbin/wpa_supplicant -iwlan0 -c/etc/wpa_supplicant/wpa_supplicant.conf -Dwext -B
sleep 2
/sbin/dhclient wlan0
echo ""
route add -net default gw 192.168.0.1
sleep 3
iwconfig
exit 0

It works, but I am not happy at all to have to run this bad script, and would like to understand the origin of this regression, and why is nl80211 not found.
