The general question is how are you allocating IPv6 addresses on these
machines? Have you had a network allocated by the provider? My guess would
be that if you haven't, on 10.04 it doesn't come up if an address isn't
available or if there isn't a link-local network available, and on 8.04 an
allocated address needs to find a link-local network or an enabled router.
