OK, what I've found out is, that I can just build a kernel using either
make or make-kpkg, and then attach the initrd using mkvmlinuz. However,
I am having some problems with this (please excuse long lines):
ppc:/usr/src/linux# mkvmlinuz -o /tmp/vmlinuz -k ./vmlinux -a prep -i arch/ppc64/boot/ramdisk.image.gz -r 2.6 -v -d arch/ppc64/boot

Anybody has a clue just where the problem (or my mistake) is?
