[…] I've successfully tested this patch on its own and with Ben Hutching's patch ("Bug#656813: [PATCH 1/2] ipw2200: Fix order of device registration", Message-ID: <1327201775.8004.83.camel@deadeye>) applied on top, it's working fine in both cases. The "cfg80211: failed to add phy80211 symlink to netdev!" warning disappears after applying both patches to kernel 3.3.2.
