Think I might have found the answer in est(4):

###
      est: CPU supports Enhanced Speedstep, but is not recognized.  
      est: cpu_vendor GenuineIntel, msr 471c471c0600471c  
      device_attach: est%d attach returned 6  

      Indicates all attempts to attach to this interface have failed.  This
      usually indicates an improper BIOS setting restricting O/S control of the
      CPU speeds.  Consult your BIOS documentation for more details.

so the next problem is out-of-band access, so not a freebsd problem.
Sorry for the noise.
