Ok, it looks nice enough indeed.
The module is not so small (354K here), so I guess this should be
shipped in a separate udeb to avoid filling initrds. This udeb would
then be available among others in the expert-mode d-i component list.
Perhaps it could be auto-loaded at partman stage, but at least making it
available would be way more convenient than fetching it by hand.
Ben, Bastian, do you think it could be added for Jessie?
