How do you change the governor from Ondemand to something else ?

The appropriate cpufreq module probably isn't loaded into that machine. Compare the output of lsmod on the broken machine against a similar machine where cpufreq is working to see what module(s) you need to load for your system.

Check with modprobe -l which module you can load. Check in /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor which governor is running. If you want to change the governor, load the module and change the sys:

echo "governor" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
