Just the merge with Debian will do it, as long as Ubuntu drops patch 0002.
Debian returned to mpath[a-z] (dropping patch 0002) a few months after Ubuntu branched off from 0.4.9-3 for Precise.
This will require changes to the installer packages; the disk-partition separator stuff can be removed (shouldn't be necessary with mpath[a-z]).
Closing the mpath[0-9]/[a-z] discussion..
