Are you suggesting that one should use cpufreq on a CPU without a

Depends on the (guest) clock source ;)
tsc isn't going to do well obviously.
kvmclock is designed to handle tsc frequency changes just fine.
And with the kvm-84 kernel module it actually works correctly.
So with Linux virtio guests I may have luck, but not so with Windows,
which can't (yet?) use kvm-clock. Correct?
(it may be some time before I'm able to upgrade and check how it really
works).
