Here is a little update on Ubuntu 14.04 dev with linux-image-generic 3.12.0.2.4:

sworddragon@ubuntu:~/data$ cpupower frequency-info && echo ---------- && taskset -c 0 sh -c "./threads.py & sleep 1 && cpupower -c all frequency-info | grep 'current CPU frequency' && echo ---------- && cat /proc/cpuinfo | grep MHz && pkill ^threads.py$"
analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which run at the same hardware frequency: 0
  CPUs which need to have their frequency coordinated by software: 0
  maximum transition latency: 4.0 us.
  hardware limits: 800 MHz - 2.70 GHz
  available frequency steps: 2.70 GHz, 2.00 GHz, 1.40 GHz, 800 MHz
  available cpufreq governors: conservative, ondemand, userspace, powersave, performance
  current policy: frequency should be within 800 MHz and 2.70 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 800 MHz.
  cpufreq stats: 2.70 GHz:14.11%, 2.00 GHz:0.00%, 1.40 GHz:0.00%, 800 MHz:85.89% (2653)
  boost state support:
    Supported: yes
    Active: yes
----------
  current CPU frequency is 2.70 GHz.
  current CPU frequency is 800 MHz.
  current CPU frequency is 800 MHz.
  current CPU frequency is 800 MHz.
  current CPU frequency is 800 MHz.
  current CPU frequency is 800 MHz.
----------
cpu MHz : 2700.000
cpu MHz : 800.000
cpu MHz : 800.000
cpu MHz : 800.000
cpu MHz : 800.000
cpu MHz : 800.000

I'm still not seeing that the processor is using 3.2 GHz.
