from the same script of debian:
if [ -f /etc/default/cpufrequtils ] ; then

        . /etc/default/cpufrequtils

fi
# if not enabled then exit gracefully

[ "$ENABLE" = "true" ] || exit 0
if [ -n "$MAX_SPEED" ] && [ $MAX_SPEED != "0" ] ; then

        CPUFREQ_OPTIONS="$CPUFREQ_OPTIONS --max $MAX_SPEED"

fi
if [ -n "$MIN_SPEED" ] && [ $MIN_SPEED != "0" ] ; then

        CPUFREQ_OPTIONS="$CPUFREQ_OPTIONS --min $MIN_SPEED"

fi
if [ -n "$GOVERNOR" ] ; then

        CPUFREQ_OPTIONS="$CPUFREQ_OPTIONS --governor $GOVERNOR"

fi
The debian way is to have a default config in the directory /etc/default, which cpufrequtils is sourcing if it exists (see script snippet above). So either you make one if you don't have one or get informed before calling such config scheme "idiocy". I don't want to be too hard in my critics but you seem to be a little too noisy too fast. Make sure you RTFM before posting such judgemental comments on distros.
