I just retested bare net-2.6.22, pulled 30 minutes ago. I got just one
warning:

eth0: no IPv6 routers present
ipw2200: Radio Frequency Kill Switch is On:
Kill switch must be turned off for wireless networking to work.

ipw2200: Failed to send WEP_KEY: Aborted due to RF kill switch.

=======================
It's 100% reproducible here, using
http://userweb.kernel.org/~akpm/config-sony.txt
The weird ASSERT_RTNL warnings aren't there, so something else in -mm
(prior to git-net.patch in the series file) would appear to be interacting
with net changes.
