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.
