I am forwarding this to the list, as it might be of general interest. This
is Xen with the last patch I sent (however, both neither Jimi nor I like
the code in that patch. More on this later). Of course, if you need to do
work on the g5 you can use the patch.
We believe at this point that integration with Mark's work should bring us
further and this is what I will try on this path (bring up on g5/Apple
mac).

(XEN) DOM0 image is not a Xen-compatible Elf image.
This is far as I get on mambo. That ERROR: postirq is from the zilog
driver.
There is no DOM0 in the boot image; I had not added the linux image. BTW,
the hardware connection is still flaky this morning, i. e., I send the
reboot command and I never hear back from the machine. I am trying now
with linux.
Jimi, I have a few changes to the patch that I sent yesterday, so let it
slide it for a few hours.
As I was writing this note, I was able to bring up the hardware. This is
as far as I get.
(XEN) Scrubbing Free RAM: .....................done.
