Thank you for the quick reply, Simon!
Sorry if I wasn't clear but the OpenFirmware is no longer able to execute GRUB2 (a PPC32 ELF), after upgrading it. The kernel is loaded by grub, and the kernel then loads the initramfs (AFAIK anyway, it's not already placed in addressable memory like ARM does with uboot).
But this gives me troubleshooting ideas, I can maybe boot the
kernel via Ethernet/BOOTP instead, which would help confirm it's
GRUB.

Hi,
my initial suspicion would be that the initramfs has grown too large, and it fails to allocate ("claim") enough memory.
You should still be able to boot the previous kernel, and build a smaller initramfs (e.g. by using `MODULES=dep`.
