A rather silly question about memory maps.

[Groman]

Hi everybody, and sorry for such silly questions, but I keep rereading the
multiboot specs that are
on the original Grub website and not finding my answers.

I've got a little kernel I'm modifying and I'm interested in making it
multiboot and load it with grub.

Question #1:
        Does GRUB at it's current CVS stage support guaranteed memory
maps?(as in the multiboot
standard)

Question #2:
        If GRUB supports memory maps, does it mark the areas where it puts
vital data as
reserved? Say the area where the kernel or a module is, is it marked as
available or reserved?

Question #3:
        If GRUB marks occupied areas as available(with modules, multiboot
info and the kernel),
how hard would it be to modify GRUB to give an option of marking those areas
as reserved?

Question #4:
        Am I totally blind and is there something about these areas in the
multiboot standard?

Thank you very much for replying.
