I don't remember the implementation for GRUB 2, since it was written by 
Jeroen instead of me. So I cannot say anything about that.

There many operating systems based on Multiboot. Just search on the web. 
You can find GNU/Hurd, L4, AtheOS, and so on.

Normally OS images are linked to 1MB or above, although Multiboot 
Specification does not mention this.

But note that you can relocate the OS image. For example, the Linux 
loader on i386 must move a kernel image to <1MB before booting it, if 
the format is zimage instead of bzimage. This stage overwrites a part 
of GRUB, but there is no problem, because the relocation code resides 
at a much lower place.
