That doesn't seem to help in my case:

root@buznote:~# modprobe -r acpi_cpufreq && modprobe -v acpi_cpufreq
root@buznote:~# cpufreq-info

analyzing CPU 0:
  driver: acpi-cpufreq
  CPUs which need to switch frequency at the same time: 0
  hardware limits: 800 MHz - 2.00 GHz
  available frequency steps: 2.00 GHz, 2.00 GHz, 1.60 GHz, 1.20 GHz, 800 MHz
  available cpufreq governors: conservative, userspace, powersave, ondemand,
performance
  current policy: frequency should be within 800 MHz and 2.00 GHz.
                  The governor "ondemand" may decide which speed to use
                  within this range.
  current CPU frequency is 800 MHz (asserted by call to hardware).
analyzing CPU 1:
  no or unknown cpufreq driver is active on this CPU
