frequency-info not available on Intel Xeon E3-1230 v2

I got a Intel Xeon E3-1230 v2 CPU, but a `cpupower frequency-info` told me the cpufreq driver is missing or unknown.

$ cpupower frequency-info
analyzing CPU 0:
  no or unknown cpufreq driver is active on this CPU
  boost state support:
    Supported: yes
    Active: yes
    25500 MHz max turbo 4 active cores
    25500 MHz max turbo 3 active cores
    25500 MHz max turbo 2 active cores
    25500 MHz max turbo 1 active cores

I've tried to load the driver module manually, but it makes no difference after a `# modprobe speedstep-lib`.

Intel claims [1] the "Enhanced Intel SpeedStep® Technology" is availabe for this CPU, and the wiki [2] says this is supported by "acpi-cpufreq", but a modprobe of this module gives me "no such device".

Please help me, thanks!

# modprobe acpi-cpufreq

Maybe?

modprobe: ERROR: could not insert 'acpi_cpufreq': No such device

Well, as I mentioned this in OP.
