Nice work...

It seems to work quite good. It's decreasing the cpu clock when system is
more or less idle.  But i have some problems with the battery <-> AC switching.

It seems it sees the ac connect state as ac-offline... 

sysctl hw.acpi.acline
hw.acpi.acline: 1

And  ichctrl ... 
Now operating on battery power; changing frequency to low speed

And it does not switch back to ac power.
