That kernel patch will fix the encryption reporting and ruin my
detection patch in any kernel where this will be incorportated. That
makes things work to some extend, but you won't get any signal strength
for the network you are connected.

Bug description:
  I filed this as a bug to network manager first 
(https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/971628). Using 
standard network-manager nm-tool (and subsequently all tools built upon nm) 
reports
  - Device: eth1  [SERVANTS-WLAN] 
------------------------------------------------
    Type:              802.11 WiFi
    Driver:            ipw2200
    State:             connected
    Default:           yes
    HW Address:        <whatever>

    Capabilities:

    Wireless Properties

    Wireless Access Points

  Apr  4 11:28:57 Marias-NB NetworkManager[1053]: <info> (eth1): using nl80211 
for WiFi device control
  (Note: the NB is connected becaus I configured the connection once, but I 
couldn't create a new one.)

  If I persude nm to use wext nm-tool reports:

  - Device: eth1  [SERVANTS-WLAN]

    Type:              802.11 WiFi

  Apr  4 11:01:59 Marias-NB NetworkManager[851]: <info> (eth1): using WEXT for 
WiFi device control
  And that's how I configured the connection in the first place.

  Perhaps this could be fixed just by disabling nl80211 in ipw2200?
