wpa_supplicant: Problems associating accesspoint

Hello!
I'm trying to associate to a Cisco Arionet 1231 (SSID tsunami, WEP key)
access point using wpa_supplicant. While manual association is no
problem, association with wpa_supplicant to this WLAN doesn't work.
Association with other WEP encrypted networks is not a problem.
My system:
Debian unstable/testing with homemade (vanilla) kernel linux-2.6.18,
patched with ieee80211-1.2.15, suspend 2 and with the ipw2200-1.2.0
modules, wpasupplicant (0.5.5-2).
The results are the same for the unpatched linux-2.6.18.
/etc/modprobe.d/ipw2200:
options ipw2200 associate=0 led=1 hwcrypto=0 debug=0x43fff
wpa_supplicant.conf:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=0
eapol_version=1
ap_scan=1
fast_reauth=1
network={
# ssid hidden
ssid="ringworld"
id_str="home_static"
scan_ssid=1
key_mgmt=NONE
auth_alg=SHARED
wep_key0=DONTKNOW
wep_tx_keyidx=0
}
network={
ssid="tsunami"
id_str="uni"
key_mgmt=NONE
auth_alg=SHARED
wep_key0=DONTSAY
wep_tx_keyidx=0
}
'iwlist eth1 scanning':

Association with 'wpa_supplicant -ieth1 -Dwext
-c/etc/wpa_supplicant/wpa_supplicant.conf -dd'
gives this result:
(see the complete log: http://www.uni-koeln.de/~a0537/wpalog.txt)
First SSID 'ringworld' is scanned and discarded. Then wpa_supplicant
scans for other networks, finds SSID 'tsunami' and tries to associate.
Both BSSIDs get skipped (skip - no WPA/RSN IE) and wpa_supplicant tells
me that it is 'Already associated with the selected AP'.
Then BSSID '00:0e:84:be:31:60' is added to a blacklist and after some
additional attempts skipped because it is blacklisted. Now the second
BSSID is blacklisted and skipped because of this reason.
It starts all over again: 'No APs found - clear blacklist and try again'.
What I see in the debug output of the ipw driver something like this:

Is there something in my configuration that I haven't found yet?
Help would be appreciated.
