I'm trying to boot a current kernel on the Efika like this:
boot hd:0 efika init=/linuxrc root=/dev/ram0 looptype=squashfs
loop=/squashfs.img cdroot

It is not finding the initrd.
I added some printks and start_initrd is not getting set.

The 2.6.19 gentoo kernel described here boots and finds the same initrd
http://gentoo-wiki.com/Efika

Something is missing in the hand off from the OF to the kernel code.
I'm poking around in powerpc/kernel/prom_init.c
looking for answers.
