I'm certain this is the way to go for 1.2, having thought about it for
a day.  Snapshot's would still be part of the LVM suit, but just
implemented in a seperate driver.

The only problem is the per device hook.  Has anyone else implemented
something similar ? or shall I just have a bash and upset the gurus.
