I don't know.  What's _PTS?

I think for the most part we want Linux to do most of the acpi work of 
bringing the machine into an idle state.  Its just that Xen is 
responsible for the very low level cpu context save/restore, because the 
Linux kernel is still running on vcpus rather than the physical cpus.
