I remember on the Xen mailing list that they wanted to encourage people
to start using Xen on laptops to help troubleshoot power management
related issues.
There's no troubleshooting to be done. It is quite simply not implemented.
There is no suspend/hibernate support. CPU scaling is useless because
Dom0 can't neccessarily see all physical CPUs, and has no info about the
activity of the guest.
The split Dom0/HV architecture is a loosing battle for ths kind of stuff
which is why we recoomend KVM as the only viable solution for laptops.
