It's not a fix, but you might want to flag it to the attention of Maemo bug 417 (https://bugs.maemo.org/show_bug.cgi?id=417) since WEP + 802.1x also requires wpa_supplicant, and your patch should allow that configuration, too, since wpa_supplicant does.

Thanks for your work on this, I'll have to give it a try to see if it works for me!
