i5-460M missing powersave scaling governor

Is it expected that an i5-460M has no option to use the powersave scaling governor? I originally thought it might be because I was using intel_pstate, but it turns out that acpi-cpufreq is being used.

$ sudo modprobe cpufreq_powersave
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_available_governors 
ondemand performance 
$ cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_driver             
acpi-cpufreq
$ grep -m1 '^model name' /proc/cpuinfo                                
model name	: Intel(R) Core(TM) i5 CPU       M 460  @ 2.53GHz

Load the cpufreq_powersave module (note, that's probably not the name of the module, but it'll be something similar). Why do you want to use powersave anyway? Despite what its name might imply, it doesn't actually save power.

Load the cpufreq_powersave module

If you had read the commands I ran in my post, you would have seen that I did.
