Hi,

I've recently installed xen-3.2.1 on my AMD Sempron(tm) machine.
It runs gentoo 2.6.21 as dom0 and cpu frequency scaling works in dom0.
But inside a domU, cpu frequency scaling is not working.
By checking the boot log in domU I found that domU is unable to load the powernow driver:
"powernow-k8: BIOS error - no PSB or ACPI _PSS objects"
I wonder if it is possible to have cpu frequency scaling support inside domUs?
