Thanks for that.  I have applied your patches to the code, and checked
in your commentary as a new document file after some editing.

I've also:

* Documented this assurance you game James:

* Documented the registry location and allocation protocol
  (qemu-xen-unstable's xenstore.c, and ask on xen-devel, respectively)

* Assigned 0xffff for `experimental' drivers in the hope that people
  won't steal one of the existing assignments.

* Assigned 2 ("gplpv-windows") for James's drivers.  James, you are
  in the best position to decide what the `build id' should look like
  and there is no need to document it other than in your release
  notes, so I'll leave that to you.

Ian.
