[opensuse-kernel] Clarification of bzImage vs gzip vmlinuz-* for -default/-xen kernels?

I'm troubleshooting a Xen boot, using recent PVGRUB, of an opensuse DomU.

@ console I see an error:

...
ERROR Invalid kernel: xc_dom_probe_bzimage_kernel: kernel is not a bzImage
xc_dom_bzimageloader.c:350: panic: xc_dom_probe_bzimage_kernel:
kernel is not a bzImage
...

I note,

file `ls /boot/vmlinuz-2*`

Is there a reason that the -default kernels are built as "bzImages",
and the -xen kernels as "gzip compressed data"?

PVGRUB's apparently had some recent patches/issues re: bzImage, gzip,
lzma compression etc; following those up of course.

This difference seems possibly relevant to the error above.

Any clarification is appreciated.
