Yes, but as i see it, kernel-package needs to be patched to allow for
the kernel-images to have different subarches in it. I need to override
the kernel-package rule file in order to build a pmac kernel image on my
pegasos/chrp related box.
Not sure though, maybe it already allows this, i will have to check it.
