    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.
