Bug Description

Binary package hint: preload

preload is highly improving the cold startup of the applications.

However it has the drawback to increase the CPU and harddisk usage.

Those 2 tasks are increasing the energy consumption.

I still want to install preload because of the responsiveness improvement but I would like it to have a smarter energy management.

By using the pm-utils package. preload could add this feature just by adding the attached script into the /etc/pm/power.d file directory.

The script above wasn't working for me under Ubuntu 12.04.2 LTS, so I created a new one that does.
