Here's some list on what i've done:
- converted the code to gas syntax... (I don't really get why, NASM is
so much better in bootloader-like things...)
- modified grub-mkrom to be able to compile it (dunno whether the
current cpp + as + ld is the correct way, but it works)
- added static offsets in image for the runtime variables...
- modified romchk to be able to modify 'em
- added grub-mkrom to be able to pass the variables to romchk (also
has --help now)
- added a tiny clean-binaries script ... it's just replacing "make
clean" for now.

And here's the new archive: (or ).

Any comments are welcomed, good or bad.
