With the stock firmware on a PrPMC800, yes, you have to attach the
ramdisk to the kernel.  You do this by copying the compressed ramdisk
image to arch/ppc/boot/images/ramdisk.image.gz.  Then do a
'make zImage.initrd'.  That will deposit a zImage+initrd image into
arch/ppc/boot/images/.

If you have a U-boot port to your board then you can be a lot more
flexible since it can load a kernel image and ramdisk separately.
