Cool.  BTW, it seems like this kind of stuff could be added to powerd 
using a timer (kqueue can do this, so you would not even have to change 
the structure of powerd too much), invoking a script with the current 
load average as an argument so the script could make the policy 
decision.

It's probably the BIOS on your system.  Check the BIOS for settings 
that might control this.  Are you using the ACPI code on your laptop?  
If not, then it's almost certainly the BIOS doing this "for" you.
