Do you happen to have a smaller disk (e.g. below 128 GB) available for
use? Or maybe you try with a separate small (512 MiB or so) `/boot`
partition directly after the HFS bootstrap partition, so the kernel is
located in the first GiB of this disk.

Thanks, Frank!  That was the clue it needed.

I used the 2019-04-12 iso for my most recent test, just incase there
was a change that might affect the problem.

I did everything the same as I did for the original test, except that
when it got to partitioning the disk, I chose guided partitioning and
“Use whole disk, with LVM”.  The LVM part forces it to create a
separate /boot partition directly after the HFS one.

That installed GRUB, which booted without a hitch.

Cool, that it worked out for you. :-) Maybe something for the Debian
wiki. We already have a machine specific part for sparc64 on [1] and
something similar for powerpc/ppc64 could be useful for new users. I
could test through my collection of B&W G3 and G4s to gather additional
info. I expect later G4s won't have such a limitation.

This firmware limitation is now documented in the Debian Wiki at [1].

Up until not I can confirm that this limitation is **not** present on a
later PowerMac3,6 (see [1] for details about the testing). I'll
subsequently test for this issue on other Power Macs and document my
findings in the Debian Wiki.
