What is the main difference with the current "cpuspeed" service? Is it the
load part? IIRC, the default /etc/cpuspeed.conf sets the CPU to run at the
lowest speed all the time when running on the battery, and also checks

I'm not sure I see the point of checking the load to change the CPU speed,
as many other things than CPU usage can make it increase (disk I/O and
network I/O come to mind). Anyway, the way cpuspeed works with my Centrino
laptop by default is fine for me : 600MHz, and it increases when I start
compiling stuff, then goes down again when it finishes :-)
