I am not quite sure I understood the request. Write my own small
firmware and replace GRUB with it? The firmware from 5/5 reads first 2
sectors and the entire PReP, I could add there stuff if that helps (I
have "work in progress" patch for the firmware with printk/etc borrowed
from SLOF).

It is incorporated into these patches under /pc-bios/vof - 4/5 has the
minimum (may be even too much), 5/5 has MBR+GPT+ELF.
