Good news for you, I found the problem. Bad news for me, I'm
apparently an idiot. Well, not quite an idiot, but I have a local
script to set up the wired interface if it's connected, and the
wireless if it's not. Somewhere in there I forgot about configuring
lo0, but it was magically being done for me. With the change that hrs
made to rc.d/auto_linklocal, the magic stopped happening, and in
focusing on the new fe80::1 address I missed the fact that the IPv4
address wasn't there. Why the change caused lo0 to stop being
configured for IPv4 is a new mystery, but that one is more in my area.
Sorry about the false alarm.

Interesting that you asked that question, it's definitely the right
track, and it's what made me go back and look harder at what I was
doing behind the scenes. Thanks!
