Comment 7 for bug 88899

This seems to happeon on my Thinkpad T60 (Core 2 Duo 2 Ghz) too:

sudo cpufreq-info

analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which need to switch frequency at the same time: 0 1
  hardware limits: 1000 MHz - 2.00 GHz
  available frequency steps: 2.00 GHz, 1.67 GHz, 1.33 GHz, 1000 MHz
  available cpufreq governors: userspace, ondemand, powersave, conservative, performance
  current policy: frequency should be within 1000 MHz and 1000 MHz.
                  The governor "performance" may decide which speed to use
                  within this range.
  current CPU frequency is 1000 MHz (asserted by call to hardware).
analyzing CPU 1:
  driver: acpi-cpufreq
  CPUs which need to switch frequency at the same time: 0 1
  hardware limits: 1000 MHz - 2.00 GHz
  available frequency steps: 2.00 GHz, 1.67 GHz, 1.33 GHz, 1000 MHz
  available cpufreq governors: userspace, ondemand, powersave, conservative, performance
  current policy: frequency should be within 1000 MHz and 1000 MHz.
                  The governor "performance" may decide which speed to use

So while Linux knows there are several modes, it only allows cpufreq to use the slowest of them...
