You mean the multiboot 2 draft?  Since this change is backward-compatible, is
there any reason we want this in multiboot 2 but not in multiboot 1?

I don't like that the two diverge so much, it makes the implementation so much
harder to maintain.  Right now the multiboot 2 loader is a complete bitrot.

Can we merge this and similar backward-compatible changes into multiboot 1?
