Tested here with two LXC containers, both of them running up to date oneiric amd64 with chattr +i /etc/resolv.conf. I then updated the sources.list for s/oneiric/precise/, updated the list and installed resolvconf. First container didn't have -proposed, the second one did.
Log for the first one: Preconfiguring packages ... Selecting previously deselected package resolvconf. (Reading database ... 11527 files and directories currently installed.)
