Is the aim to be able to boot from any device that can be plumbed to qemu,
or to allow kernel/initrd parms to be specified from outside the HVM
bootloader config file? If the former, Anthony Liguori's recent patch to
implement an option ROM to allow easy cut-thru to any qemu backend device
looks like an easier way to achieve that aim.
