I am working with the MPC8540 in a mobile product and some power saving would be fine to use. But I haven't seen any power management code for that thingy in the kernels at all. So, there is some work left there. Maybe I will have a closer look in the future. According to some tests of a board manufacturer, the cpu doesn't power down very much, when you stop some peripherals or send the core to nap. But I wasn't able to confirm that yet.
