Here is the output of the command dmesg|grep power now
[ 6760.985893] powernow-k8: Found 1 AMD Athlon(tm) 64 X2 Dual Core Processor 5000+ processors (2 cpu cores) (version 2.20.00)

And I also checked from /sys/devices/system/cpu/cpu0/cpufreq
scaling_available_governors have "userspace performance"
scaling_governor is "userspace"
scaling_driver is "powernow-k8"
Seems the "ondemand" governor is missing, how could I add it back and change the scaling_governor?
Thanks.
