We can allow d-i grub installation on powerpc machines for wheezy, but
not make it default.

To transition fully to grub on powerpc machines we will have to change
partitioning recipes for CHRP IBM, CHRP Pegasos and NewWorld Mac
machines. This will have to wait for jessie.

Manual creation of the appropriate partition in d-i (/boot/grub) will
enable grub installation in wheezy d-i. Thus, we will be able to
experiment with d-i grub installation on powerpc machines.

I agree.

Do you have access to any IBM Power machines?
