Hmm. I could create an updated debian-installer image for powerpc and
see if it works there. I might just be missing something, maybe in
the grub2 package itself.

Interesting. I guess they made that to make the user interface more consistent.

You are right then, of course. But I from debian-installer point of view,
it's still treated as a flag. So, I think we need to check where that
is normally set.

But my main guess is now that the grub2 needs additional changes currently
missing for ppc64.
