Yeah, yeah, that was exactly what I was saying by "describing the rest
of the whole disk as a single chunk containing GPT managed area" with
a typo making "whole" "while".

Sure it's not but MBR belongs to the boot loader not the BIOS.  BIOS
just needs to load MBR and handles control to it.  If the MBR or more
likely later stages of the bootloader loaded by MBR knows how to boot
from GPT, it should work.

I'm not sure about grub although I strongly suspect recent version of
it should work but AFAICS lilo should definitely work as it doesn't
care how the disk is logically organized at all.

Thanks.
