     Ok, I've done these 2 things and the output is at:

http://pridelands.org/~simba/xen/hailstorm-fullserial20110609-02.txt

     After changing dom0_mem to 1G instead of 512M, the machine hangs at
"Switching to clocksource xen" instead of "Trying to unpack rootfs image
as initramfs..."

     As an added step, I also recompiled the latest Mercurial pull of
xen-unstable.hg and am running with that instead of the one I had from a
month or so ago.  I'm not sure if that is what is making it not end up
with a Kernel OOPS/BUG message or if it is the apic=debug option.

     acpi=off is definitely not on the command line, now, though, and
it's not giving the OOPS that it was before.  It's just hanging/freezing.

     I did not see an attachment on your last e-mail.
