    :-)     nobody said it would be easy

My guess is that redboot binaries have another header format,
then the pxelinux.0 has.

An simple check would be doing

  file pxelinux.0

and

  file a_redboot_executable


After prepending pxelinux.0 with the redboot header info,
you will mostly likely will be missing PXE code in the redboot boot ROM.


My advice is to contact the people from the Etherboot project,
if you want to continue with "pxelinux.0 on redboot"

P.S.

I wonder why to load pxelinux.0 to load a kernel,
where redboot can load a kernel at once ...
