Hi,

the sysfs-interface of intel_pstate is different to that of the acpi driver:
- intel_pstate shows current cpu-frequency in "cpuinfo_cur_freq" whereas
  the acpi counterpart uses "scaling_cur_freq".
- moreover cpuinfo_cur_freq is readable by root only, whereas
  scaling_cur_freq is world readable.

  A monitoring tool must take care of theese differences.
  Is this intentional?

Thanks, Jörg
