In fact, I've installed a debian sarge on an external disk drive with  
my iBook G4 and I use this image with qemu.

Then I cross-compile a linux kernel from GIT and I use yaboot (I've  
compiled it on x86_64) to update the disk image:

kpartx -a sarge-ppc.img
mount /dev/mapper/loop0p3 mnt
cp linux-2.6/vmlinux mnt/boot/vmlinux-2.6-test
sudo umount mnt
yaboot-1.3.14/ybin/ybin -o hd:2 -b /dev/mapper/loop0p2 --config  
yaboot.conf --nonvram
kpartx -d /dev/loop0

My yaboot.conf is:

boot=/dev/hda2
device=hd:
partition=3
root=/dev/hda3
timeout=5000
install=yaboot-1.3.14/second/yaboot
magicboot=yaboot-1.3.14/first/ofboot
enablecdboot

image=/boot/vmlinux-2.6-test
	label=Linux-test
	read-only
	append="console=ttyS0"

image=/boot/vmlinux
	label=Linux
	read-only
	initrd=/boot/initrd.img
	append="console=ttyS0"

image=/boot/vmlinux.old
	label=old
	read-only
	initrd=/boot/initrd.img.old

On an install CD there is a forth script which start yaboot with good  
parameters but currently OpenBIOS is not able to decode this script  
(inside XML tags).
