I've got a couple of distributions installed, Gentoo with GRUB2, and openSUSE with some other version of GRUB.
OpenSUSE manages it's kernel entries, and I don't want to have to update my main Gentoo GRUB2 config to copy changes after updating. Currently I hit F8 in the BIOS to select a different disk, but it'd be nice to just go from my main GRUB to openSUSE managed GRUB via a menu entry.
How do I get GRUB2 to load GRUB from another disks MBR?
How do I get GBUB2 to load GRUB from another bootable partition?

Assume I'm on
hd0 MBR, and booting to GRUB in
hd1 MBR, or
(hd1,2) (Second partition).
