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):
