And now with actual applies action...

Sorry for the previous one; try this one instead.

In order to be able to move proper cpu throttling along I want to get
the following diff in. It adds support for _PPC which defines which
power states are available after a cable pull or insert. An example is
my Dell D810; if I use a 65W power suppoy I can only run at 800MHz; if I
run unplugged I only have 5 out of 6 power states (depending on the
battery) and when plugged in to 90W power supply it has all power states
available. It also gets the code ready for the addition of duty cycle
throttling (only run the cpu every so many clock cycles). When both
those are in we can move forward to making acpitz do throttling based on
thermal requirements but those diffs are still a few days away.

Please test and send me a report of success / failure. I Particularly
need testing on amd64 laptops.
