I don't think powerd will change the Cx level by default, but it should change the frequency as reported by dev.cpu.X.freq where X is the CPU number. You should be able to have the Cx levels change by setting dev.cpu.X.cx_lowest to something other than C1, but I think you need to keep CPU 0 at C1 otherwise the system will stop working properly (timings will change).
