Yeah, it's a work in progress.  I have some test patches to extend the
bzImage format to contain ELF notes, and a corresponding Xen patch to
add a new file format for the domain builder. But its a bit
up-in-the-air because nobody has agreed to the bzImage format changes,
and its all a bit subtle to make sure it keeps working with a wide range
of fairly poorly implemented bootloaders.
