Bug Description

CPU frequency scaling doesn't work. If you run /usr/sbin/laptop_mode by hand, you'll get an error on line 606 about writing an invalid value.

That line is currently:

echo $THIS_GOVERNOR > $THISCPU/cpufreq/scaling_governor

It should be (i.e. add _CPU):

echo $THIS_CPU_GOVERNOR > $THISCPU/cpufreq/scaling_governor

This makes the CPU scaling work properly.
