Well it works only in the sense that make completes with no errors
producing a rather large xen file :). However, the file does not boot
on hardware nor does it boot on the simulator (mambo). I suspect a
file format error
On the simulator:

There are a few gremlins here, such as where boot: k42 came from and how
is exactly yaboot not getting in the way. I should add that a plain
xen, i. e., one without vmlinux, get further in the startup sequence
than this one. It stops only when it cannot find a dom0 image, as it
should.

What command do you use to build the xen blob (xen with vmlinux in it)?
To build a dom0 blob into xen (on PPC) simply add
DOM0_IMAGE=<path to image>
to your make line.
This _should_ work.. please post if it does not.
What about building a linux image with initrd?
$ make -C linux zImage.initrd
When it fails it will tell you where you need to put your initrd :)
There is also a way to do it with a cpio archive but not sure how to
do that.
Where to get an initrd is an exercise for the reader :)
