Yes and no. The BUG no longer occurs, but either ipw2200 or NetworkManager is still not working. I am running Fedora development (rawhide). For some reason, NM still cannot establish a connection with this kernel build (this failed with 2.6.18-mm2 previously, but I thought it was related to the BUG). "iwlist scan" can corrently detect my access point. Also, I can use iwconfig and dhclient to establish a working connection. NM fails with this output in the message log (I'll try getting a more detailed debug log out of NM):
