Please check out ondemand script from ubuntu

[Petter Reinholdtsen]

Hi.  Please check the ondemand script in
<URL:http://patches.ubuntu.com/s/sysvinit/sysvinit_2.86.ds1-61ubuntu13.patch>.
In debian, that work is done by the cpufrequtils package you
maintainer, and I suspect it stay that way in Debian.  I believe
ubuntu did it this way to avoid having to pull in the cpufrequtils
package in every installation, but am not sure.

Happy hacking,
