Sorry if I am not being very smart  here, confused by the remark "
bzImage support would not be possible"

I was able create wrapped image using command

wraplinux -p "console=ttyS0,115200" -i initrd.gz -o
vmlinux.initrd.wrap arch/i386/boot/bzImage

I am using wraplinux version 1.6

if I use any other image  wraplinux doesn't find the version
information and initrd image doesn't get attached.

What file should I be specifying as the 'kernel' when I execute
wrapimage  if not the bzImage?

( I am working with 2.6.23 kernel)

On my board I can boot the standard bzImage, but not able to load the
wrapped image produced by wraplinux command. Would very much
appreciate hints...
