I think Ben's solution (the BootX file he shared) is just an
openfirmware script that runs before grub, which allows you to choose
between a grub/os x/CD. And it is also how yaboot handled this (I
think his script is a modification of the yaboot one). But I am not
sure how to make that script run by default instead of jumping
straight to grub.

Although grub shows options for the other installed operating systems
(i.e. OS X) it indeed seems unable to boot them. I am not sure if this
is supposed to work.
