        "The command in your /etc/rc.local file only works if you
        disable the ondemand service. On Debian systems:
        sudo update-rc.d ondemand disable
        Another option would be to modify the ondemand init script and
        rename it to performance:
        sudo sed -i 's/ondemand/performance/g' /etc/init.d/ondemand
        sudo update-rc.d ondemand disable
        sudo cp /etc/init.d/ondemand /etc/init.d/performance
        sudo update-rc.d performance enable"

Last time I used Debian there was a script /etc/init.d/cpufrequtils that
set up the governor to ondemand. It's not that long ago, so I guess for
Debian this didn't change. Len of course refers to Ubuntu (Studio).
AV Linux (Debian) also has got /etc/init.d/cpufrequtils:

# Set ENABLE to "true" to let the script run at boot time.
# eg:	ENABLE="true"
#	GOVERNOR="ondemand"
#	MAX_SPEED=1000


I once wrote a script to toggle between ondemand and performance, not
only for the session, but also to keep it for next startup, based
on /etc/init.d/cpufrequtils.
