powerd rc script failing to start after fresh build

Synced to r298678 this evening and after a reboot, powerd fails to start
with the following error in messages:

  Apr 26 17:54:12 titan root: /etc/rc: WARNING: failed to start powerd

Manually trying to start it via service throws:

  $ sudo service powerd start
  Starting powerd.
  powerd: no cpufreq(4) support -- aborting: No such file or directory
  /etc/rc.d/powerd: WARNING: failed to start powerd

dmesg shows:

This wasn't the case till the update today, including the ACPI BIOS
warning.

Any help appreciated or let me know what else I can provide to help find
the root cause.

Thanks,
