During my latest round of trying to get this working, while referring to a different section of the Gentoo GRUB wiki, I noticed that it is necessary to give an output argument to grub-mkconfig, which I had not been doing, so it is entirely possible that any or all of the previous suggestions would have worked, had I actually written them to /boot/grub/grub.conf.

That seems like a very reasonable point. I tried adding another entry in the form that you originally suggested, and it works, too.  So now I have both a direct boot GRUB menu entry and a chainload entry.
