Yes, A mini-driver to hook into ppc_md.progress would be one method.
Another would be to do what's needed (I don't know off-hand what, sorry)

early_printk.c stuff (see arch/x86_64/kernel/early_printk.c) does.

204 42...45 (devices.txt in linuxppc-2.5, Pantelis ever figure out what
to do about the device # conflict with the i.MX driver so we can push
