Jeff what is your concern.
The boot protocol change is in 2.6.21 for arch/i386.
HPA looked at it a while ago.
All it does is set a flag that tells a bootloader.
"Hey. I can run when loaded a non-default address, and this is what
you have to align me to."
All relocation processing happens in the kernel itself.
So it is all pretty trivial.
