Oh, and one more clarification about this. Upcoming Debian stable
release ("Squeeze") will have Xen dom0 using the forward-ported patches.

See: http://lists.debian.org/debian-kernel/2009/10/msg00613.html

Debian's plan is to remove the forward-ported Xen dom0 patches after
Squeeze, and then use upstream Linux pv_ops dom0 support.
