Well, the output was from the kvm where I tried to boot xen with the
same config as on my rootserver, where I don't have access to the
console output to see why it doesn't boot. :)

Only on my rootserver. Just tried it again just in case and it
still doesn't boot if I remove the "noapic acpi=off" options.
(And it seems to blow up before I get any output over netconsole)
I should try it on my notebook I guess, though that is a Core2 Intel
with Vanderpool IIRC, so it may behave differently there.
