I am not sure the exact version of my source. it comes from XenPPC project who
maintains a separate Linux tree from the "sparse tree" that comes with Xen.
-----------------------------------------------
$ mkdir ~/xen
$ cd ~/xen
$ hg clone http://xenbits.xensource.com/xen-unstable.hg
$ mkdir ~/xen/linux
$ cd ~/xen/linux
$ hg clone http://xenbits.xensource.com/ext/linux-ppc-2.6.hg
$ mkdir ~/xen/linux/xen
-----------------------------------------------
The gcc version 4.1.2_20070115 was used to build the boot image, which shipped with SLES 10 SP1.

Here below is the command line used:
make -C ~/xen/linux/linux-ppc-2.6.hg ARCH=powerpc O=../xen xen_maple_defconfig
make -C ~/xen/linux/linux-ppc-2.6.hg ARCH=powerpc O=../xen zImage
<cp ramdisk.image.gz ~/xen/linux/xen/arch/powerpc/boot/ramdisk.image.gz>
make -C ~/xen/linux/linux-ppc-2.6.hg ARCH=powerpc O=../xen zImage.initrd
make -C /root/xen/xen-unstable.hg/xen/ DOM0_IMAGE=/root/xen/linux/xen/arch/powerpc/boot/zImage CMDLINE=" -- root=/dev/disk/by-id/ata-TOSHIBA_MK4019GAXB_93SK3653T-part3"
I am attempting to boot Xen/Dom0 instead of the installed Linux kernel.
Since the boot loaded is yaboot, I added a new entry in /etc/yaboot.conf that boots Xen instead.

The "xen" yaboot is:
image = /boot/xen
label = xen
root = /dev/disk/by-id/ata-TOSHIBA_MK4019GAXB_93SK3653T-part3
initrd = /boot/zImage.initrd
And also, the original yaboot is:
image = /boot/vmlinux-2.6.16.46-0.12-ppc64
label = linux
root = /dev/disk/by-id/ata-TOSHIBA_MK4019GAXB_93SK3653T-part3
initrd = /boot/initrd-2.6.16.46-0.12-ppc64
