Using xenstore-ls from the dom0 on the guest when the boot stops the 
local/domain/2/device/vbd/51712 section looks like
       backend = "/local/domain/0/backend/vbd/2/51712"
       backend-id = "0"
       state = "6\000"
       virtual-device = "51712"
       device-type = "disk"
       ring-ref = "\000"
       event-channel = "\000"
       protocol = "x86_64-abi\000"

As nothing else has null character endings I suspend that is wrong.
