what does it say if you do 
lsmod|grep cpufreq
and then what does it say if you do
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors
what happen if you do say
modprobe cpufreq_ondemand
then
echo ondemand>/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
or do you have trouble compiling these governors at all?
