  Thank you very much, that was it.  I actually use lilo, so stuff like

        append = "noexec=on net.ifnames=0 intel_pstate=disable"

  I now get available frequencies (in khz) for the Silvermont of...

  [7]   1601000
  [8]   1600000
  [9]   1520000
  [10]  1440000
  [11]  1360000
  [12]  1280000
  [13]  1200000
  [14]  1120000
  [15]  1040000
