Apparently there is something that doesn't work here. Either dnsmasq
doesn't see the request, or discards it when it shouldn't.  I'm going to
try and find out later.  There's a couple of reasons this could fail,
but the reason is _not_ that FreeBSD 8.2 couldn't bind INADDR_ANY with
named bound to 127.0.0.1:53 TCPv4 and ::1/53 TCPv6.
