so, just to clarify, i'm looking at arch/ppc/boot/simple/Makefile, the
excerpt:

$(obj)/zvmlinux.initrd: $(OBJS) $(LIBS) $(srctree)/$(boot)/ld.script \
                 $(images)/vmlinux.gz $(obj)/dummy.o
         $(OBJCOPY) $(OBJCOPY_ARGS) \
-->             --add-section=.ramdisk=$(images)/ramdisk.image.gz \
 		--set-section-flags=.ramdisk=contents,alloc,load,readonly,data \

and all i need to change is "ramdisk.image.gz" to, say, my "newc"
format gzipped cpio archive, "initramfs.cpio.gz", and the early kernel
code should recognize it as such automatically?

i'll give that a shot later.
