I had a look on the boot partition native AIX.
Besides the AIX logical volume control block, things are the same as described
in Leigh's doc : PC compatibility blok, Entry point offset, Load image length
and so on.
Once loaded ("load disk"), the memory mapping is the same, flags are the same,
registers are ok (ppc points on entry point ). Image loaded is greater than
vmlinuz..... so I don't think its a size problem.
And AIX boots, of course.
Remembering that yaboot (ELF) loads and goes (not very fine) I have no idea
Just a difference/bug in this OF whith the client interface ? Something in
Linux code not accepted here ?
Should it be this strange thing: RSPC between PReP and CHRP ?

That seems rather difficult for me but I am searching.
