grub.cfg is the same in both mini.iso and debian-testing-ppc64el-netinst.iso.
With the failing debian-testing-ppc64el-netinst.iso, I also noticed that when
I define "cdrom" alias in the openfirmware, grub loads its menu.
--- in the openfirmware :
0 > devalias
ibm,sp /vdevice/IBM,sp@4000
network /vdevice/l-lan@30000002
net /vdevice/l-lan@30000002
scsi /vdevice/v-scsi@30000015
nvram /vdevice/nvram@4002
rtc /vdevice/rtc@4001
ok
0 > devalias cdrom /vdevice/v-scsi@30000015/disk@8200000000000000 ok
0 > boot cdrom

Grub shows the menu and in grub's command line, I have :
---
grub> set
?=0
cmdpath=(ieee1275/cdrom,5)
color_highlight=black/light-gray
color_normal=light-gray/black
default=2
feature_200_final=y
feature_all_video_module=y
feature_chainloader_bpb=y
feature_default_font_path=y
feature_menuentry_id=y
feature_menuentry_options=y
feature_nativedisk_cmd=y
feature_ntldr=y
feature_platform_search_hint=y
feature_timeout_style=y
grub_cpu=powerpc
grub_platform=ieee1275
lang=
locale_dir=
pager=
prefix=(ieee1275/cdrom)/boot/grub
root=ieee1275/cdrom
secondary_locale_dir=
---
Without doing devalias, it's failing to load the menu and I have :
---
grub> set
?=0
cmdpath=(ieee1275//vdevice/v-scsi@30000015/disk@8200000000000000,5)
color_highlight=black/light-gray
color_normal=light-gray/black
feature_200_final=y
feature_all_video_module=y
feature_chainloader_bpb=y
feature_default_font_path=y
feature_menuentry_id=y
feature_menuentry_options=y
feature_nativedisk_cmd=y
feature_ntldr=y
feature_platform_search_hint=y
feature_timeout_style=y
grub_cpu=powerpc
grub_platform=ieee1275

So it seems that the value cmdpath in grub is different and changes the
behaviour. Grub shows version "2.02~beta2-36".
mini.iso which works without the devalias workaround, shows the good value of
cmdpath i.e. (ieee1275/cdrom,5) and shows "2.02~beta2-36". So I think your commit is good.
But the 2 grubs behave differently in determing cmdpath value.
They also show the same version.

How does that come ? Do we have different versions of grub actually for testing
mini.iso and testing netinst ? or are those binaries build differently from the
same source, one missing some functionnalities.
I'm still trying to make debian-cd work on my side :)
