Yep, that's about right. I will implement that later today. Thanks
for pointing
me at that.
I have patched partman-prep now [1]. Interestingly, it used to have ppc64
support and it was removed [2].
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/.
One can simply install GRUB on these systems now by choosing "Back" in the
yaboot-installer menu and then choosing to install GRUB.
I today did a "normal" and an expert install with successful GRUB
installation with the [installer ISO] from 2017-10-10 and can confirm
that both also work on POWER5 systems, specifically on a 9131-52A.
If anyone on the list has a POWER3, POWER4 or POWER6 system available,
it would be interesting to see, if this works for these out of the box, too.
[installer ISO]:

If you are unable to boot your POWER5 system with this disc with similar
messages than the following ones:
```
Config file read, 1342 bytes
Welcome to Debian GNU/Linux sid!
This is a Debian installation CDROM,
built on 20171012-17:54.
Enter one of the following options to begin:
install 64-bit processor (G5 or POWER3/4/5/6/7)
install32 32-bit processor (G4 or earlier)
Press TAB for a full list of options.
If the system fails to boot with a white screen
which doesn't go away, add 'video=ofonly'.
Welcome to yaboot version 1.3.17
Enter "help" to get some basic usage information

```
...then try the following OF commands to wipe your NVRAM (you'll loose
your configuration there, though) and retry:
```
dev nvram
wipe-nvram
```
...as per [1] and [2]. This made booting from the disc to work for me then.
