yes, this works better :

kldload cpufreq :

  hwpstate0: <Cool`n'Quiet 2.0> on cpu0
  hwpstate0: SVI mode
  hwpstate0: you have 2 P-state.
  hwpstate0: freq=2400MHz volts=1300mV
  hwpstate0: freq=1200MHz volts=1050mV
  hwpstate0: Now P0-state.
  hwpstate1: <Cool`n'Quiet 2.0> on cpu1
  hwpstate1: SVI mode
  hwpstate1: you have 2 P-state.
  hwpstate1: freq=2400MHz volts=1300mV
  hwpstate1: freq=1200MHz volts=1050mV
  hwpstate1: Now P0-state.
  hwpstate2: <Cool`n'Quiet 2.0> on cpu2
  hwpstate2: SVI mode
  hwpstate2: you have 2 P-state.
  hwpstate2: freq=2400MHz volts=1300mV
  hwpstate2: freq=1200MHz volts=1050mV
  hwpstate2: Now P0-state.
  hwpstate3: <Cool`n'Quiet 2.0> on cpu3
  hwpstate3: SVI mode
  hwpstate3: you have 2 P-state.
  hwpstate3: freq=2400MHz volts=1300mV
  hwpstate3: freq=1200MHz volts=1050mV
  hwpstate3: Now P0-state.

however, I need to disable acpi_throttle;
standard, I get :

  [root at m34 ~]# sysctl dev.cpu.0.freq_levels
  dev.cpu.0.freq_levels: 2398/-1 2098/-1 1798/-1 1498/-1 1199/-1 899/-1 599/-1 299/-1
  [root at m34 ~]# kldload cpufreq
  [root at m34 ~]# sysctl dev.cpu.0.freq_levels
  dev.cpu.0.freq_levels: 2400/-1 2100/-1 1800/-1 1500/-1 1200/-1 1050/-1 900/-1 750/-1 600/-1 450/-1 300/-1 150/-1
  [root at m34 ~]# powerd -v
  powerd: unable to determine AC line status
  idle time > 90%, decreasing clock speed from 2398 MHz to -1 MHz
  powerd: error setting CPU frequency -1: Invalid argument
  idle time > 90%, decreasing clock speed from 2398 MHz to -1 MHz
  powerd: error setting CPU frequency -1: Invalid argument

rebooting with hint.acpi_throttle.0.disabled="1" gives :


  [root at m34 ~]# sysctl dev.cpu.0.freq_levels
  sysctl: unknown oid 'dev.cpu.0.freq_levels'
  [root at m34 ~]# kldload cpufreq
  [root at m34 ~]# sysctl dev.cpu.0.freq_levels
  dev.cpu.0.freq_levels: 2400/-1 1200/-1
  [root at m34 ~]# powerd -v
  powerd: unable to determine AC line status
  idle time > 90%, decreasing clock speed from 2400 MHz to 1200 MHz
