During work on multiboot2 protocol support for Xen it was discovered
that memory map passed via relevant tag could not represent wide range
of memory types available on EFI platforms. Additionally, GRUB2
implementation calls ExitBootServices() on them just before jumping
into loaded image. In this situation loaded system could not clearly
identify reserved memory regions, EFI runtime services regions and others.

Will a multiboot2 tag with whole EFI memory map solve your problem?
I added such a tag in documentation and wrote a patch for it (attached).
Awaiting for someone to test it to commit

Great! I think from Xen perspective we first need to have Xen be able
to understand multiboot2 - that is something Daniel had been working on.
I will let Daniel talk more about it.

Seth, would you have any time to test the patch against Solaris to
make sure it works?

  I'd love to, yes.  I'm just a bit short on time this week.
