The bug still exists for me on my Dell Vostro 1700, and my computer only
runs at 800MHz which makes it slow and unsuitable for watching HDTV
movies.

I installed the cpufrequtils and ran cpufreq-info, se output below. The most 
interesting line is probably:
  current policy: frequency should be within 800 MHz and 800 MHz.

Is this problem just about changing this policy? And how is that done?
