Sorry, I'm more than busy with writing an OS <advertize> http://v2os.v2.nl
</advertize> and I don't know much C (just enough to read it).

Well, "fully compliant" were the wrong words. Here's a quote from the last
section of the Multiboot specification that I had in mind:

    The GNU GRUB (see section `GRUB' in The GRUB manual) project is a
    full Multiboot-compliant boot loader, supporting all required and
    optional features present in this specification.

I therefore believed that loading below 1 MB will be supported sometime.
