I tried using the ipw2200 driver found in gentoo-source 2.6.18, 2.6.19 and 2.6.20 for connecting to an AP with EAP-PEAP/MSCHAPv2 authentication. In the output of wpa_supplicant -Dwext there is the following line repeated Driver did not support SIOCSIWENCODEEXT Using the net-wireless/ipw2200 driver and the same wpa_supplicant configuration, everything is ok Reproducible: Always
Please attach kernel .config

Created attachment 116172 [details] Kernel configuration requested Sorry, I am very late but this PC was always out of the office. The attachment is the configuration you required.
Now you can test..
I think you may have attached the wrong kernel .config -- it shows that you are not compiling the ipw2200 driver into the kernel.
