Unfortunately, you are now dragging me up onto the rocky shores of my 
knowledge... so this is going to get a little experimental.

First thing I'd try is removing the initrd line from new-kernel section of 
yaboot.conf.  Since the error seems to be coming from the ramdisk, this 
might solve the problem.  Having an initrd image is not necessarily 
needed, so that could fix the whole problem.  If not, report back and we 
can try building an initrd image from the new kernel.
