there should be, but i am not familiar with this. Look into Documentation directory of a kernel tree for details. BTW, while you are at the serial OF prompt, could you try booting : http://people.debian.org/~luther/d-i/images/daily/powerpc/netboot/vmlinuz-coff.initrd directly, it should work, and was made especially for this kind of case.
