I've tried it on My Apus2000/200 with OpenFirmware 2.0,
then it also fails.

Boot floppies from NetBSD 5.2.3 works.
6.1.5 and 7.2 ones also fail.

It looks APM support added from 6.x causes the problem
because the boot1 floppy has faked apple partition map,
 https://nxr.netbsd.org/xref/src/usr.sbin/installboot/arch/macppc.c?r=1.11#94
so your analysis in the PR port-macppc/53727 seems correct.
 https://mail-index.netbsd.org/netbsd-bugs/2018/11/12/msg059608.html

Note the apple partition map is required by only OFW 1 and 2 machines, IIRC.
