I thought that with this initial merge, we stll had to build separate
images for bare metal vs Xen paravirt because of the way Linux uses
the bzImage, while Xen is in ELF format ? Or has this bootup difference
already been resolved ?


I think that is correct. Work is (from what Jeremy said) in progress to make a "compatible format" for both uses.
