Good news: With partman-prep enabled on ppc64 and after adding the hack
to wipe
and find the PREP partition on powerpc and ppc64 in grub-installer [1], the
installation of GRUB on ppc64 works now out of the box on my POWER7
system \o/.
Good to hear! :-)
One can simply install GRUB on these systems now by choosing "Back" in the
yaboot-installer menu and then choosing to install GRUB.
Now we only need to get it working on NewWorld Macs :).
Yeah, that seems to be a hard nut to crack. But I believe I'm making
some progress - in understanding at least :-D.
Regarding hfsutils:
Here's a patch for grub-installer (package source) that should hopefully
install hfsutils from the `debian/postinst` script (adapted from
yaboot-installer) for the newworld_powermac subarchitecture(s) only:

What is the meaning of those "# :sl<NUMBER>:" comments, if at all? I
didn't find any clue in the debconf specification [1] and manpages [2].

Last, how can I test this? Is there a way to inject "my" version of
grub-installer.udeb into a Debian installation without recreating the ISO?
Cheers,
Frank
