Details:
I'm the ppc64 maintainer for the Adélie Linux distribution. We're trying to
craft a bootable CD for the Power Mac G5 and IBM pSeries. We don't have the
pSeries here yet for testing, but we do have a Power Mac G5 (dual 2.0 GHz,
PCI-X).
I'm seeing the following on-screen when booting either from OF (boot
cd:,\boot\grubcore.img) or letting the machine boot from CD "normally" using
the "C" key (tbxi):
Welcome to GRUB!

Invalid memory access at %SRR0: 00000000.00000f20 %SRR1: 90000000.00810000

This happens very early on. The 32-bit PowerPC build that we have of grub
2.02 boots fine on the same hardware, so it seems specific to the 64-bit
port.
I added "set debug=all" to the embedded image "early" config file, and
rebooted. I received the exact same output. Please let me know if there is
another (possibly undocumented?) method of causing GRUB to print more debug
information.
