Well, I tried. Added simple MBR+GPT parser, loaded ELF and discovered
that load_elf32/64 does not parse ELFs from memory, only from files.
Anyone keen on fixing that? :) My current workaround is to load grub
from the disk, then store it /tmp and load this as it was passed via
-kernel which is ugly..
