I am starting to make some headway on my os-prober / grub2 issue.

Today, there was a new kernel for Natty. When it installed, it gave a grub2 syntax error. I got around the error by running install-grub, which ran without error, but again failed to detect Maverick on the other partition. When I rebooted to Natty, it was using the new kernel.

But, as Maverick is my main-use installation, I have to be able to boot to it. So, once again, I booted to the Maverick Live DVD and installed Maverick's grub2. That detected both Maverick and Natty. Maverick booted fine, but when I booted Natty, it was back on the previous kernel version.

So, on a hunch, I manually ran os-prober in Natty, then ran grub-install, again. That did the trick. I can now selectively boot Natty or Maverick, and when I boot to Natty, it runs the current latest kernel.

This is all to say, things are still quite a mess, but I have learned how to force them to work.
