There isn't any expectation that our bootloader passes the correct
things in the multiboot structure to satisfy the multiboot entry point
of a NetBSD kernel.

Even if someone fixes this I don't feel that we should claim that it is
supported, it just multiplies up the number of things that could break
and need to be tested.

If someone reports that grub can longer boot a NetBSD kernel then that
is maybe more of an issue.

I know, that is why I added multiboot to the bootloader.
