This is also the problem behind bug 1579278 which recently affected an
IS machine. Forcing "powersave" on all newer x86 CPUs is a bug.

Title:
Since the /etc/init.d/ondemand script has many other issues, including
overriding the settings prepared by /etc/init.d/cpufrequtils, I think
that the best option should be removing it.

May I also chime in? If I wanted my machine to run at Celeron speed, I
would not have bought a core i5. I think it makes no sense to select
the "powersave" governors by default without telling the user in any
way. Any non-expert user will not know why his machine runs 2x more
slowly on Linux
This behavior is a deliberate result of the change made for bug
#1314653. Assigning to the developers responsible for that change.
Colin, Tim, please evaluate whether a more nuanced selection of scaling
governor is required.

Only interactive, ondemand and powersave appear to be handled:
*interactive*)
GOVERNOR="interactive"
break
;;
*ondemand*)
GOVERNOR="ondemand"
