### CPU frequency scaling modules:
# generic ACPI P-States based driver
/sbin/modprobe apci-cpufreq
# AMD mobile K6-2/3+ PowerNow!
/sbin/modprobe powernow-k6
# AMD mobile Athlon PowerNow!
/sbin/modprobe powernow-k7
# AMD Cool&Quiet PowerNow!
/sbin/modprobe powernow-k8
# Intel SpeedStep using the SMI BIOS interface
/sbin/modrobe speedstep-smi
# Intel SpeedStep on ICH-based chipsets
/sbin/modrobe speedstep-ich
# Intel Enhanced SpeedStep
/sbin/modrobe speedstep-centrino
# Intel Pentium4/Xeon clock modulation
/sbin/modprobe p4-clockmod
# NatSemi Geode GX / Cyrix MediaGXm
/sbin/modrobe gx-suspmod
# Transmeta Crusoe / Efficeon LongRun
/sbin/modrobe longrun
# VIA Cyrix Longhaul
#/sbin/modrobe longhaul
# NFORCE2:
/sbin/modrobe cpufreq-nforce2

### CPU frequency scaling policies:
# Powersave policy, stick frequency to the slower state.
/sbin/modprobe cpufreq_powersave
# Performance policy, stick frequency to the faster state.
/sbin/modprobe cpufreq_performance
# Set the frequency on demand. What you want is what you get
/sbin/modprobe cpufreq_ondemand
#echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
# Same of On demand policy, but for slow switching CPUs (AMD64 e.g)
/sbin/modprobe cpufreq_conservative
