Powertop on Beagle
I'm trying to get powertop running on the latest git. It basically works, but I do not get displays for the C and P states. This has worked in the past, but the OE kernel I'm using had a lot of patches then :)
Does anyone have a list of things to check, before I start working through my kernel patch history?

For kernel:
You need cpuidle in kernel and configured on. You need to enable timerstats under kernel debug options.
For Userspace:
You need powetop binary
You need ncurses package installed

The older kernel applied CPUidle patches, which are in the PM branch nowadays.
