Except that this ought to be marked (external) in the first place:
The hypervisor support is all there (otherwise our kernels wouldn't
have been successfully booting on EFI for well over a year), and
hence this work shouldn't really have any impact on the schedule.

The one feature here that requires work in our tree is to be able
to boot via grub.efi (irrespective of how little I personally like that);
I'm not sure Daniel was also planning to look into that part.
