I guessed that would be the case. The bringup for a restore would be 
quite straighforward but more complex for migration. Has anyone 
suggested hooks for xend to deal with 3rd party drivers so that it could 
initialise and restore devices that are supported by these drivers?  
This would enable new drivers to be implemented without changes to xend.
