There are people (even OEM btw) that sometimes think that throttling a
CPU is the same as for P-state.

And? You are using the cpufreq infrastructure with the enhanced
speedstep driver, which is the same thing anyway.

Well, if really you last only 2 hours and a half on battery, even if
running at 600MHz via cpufreq, and C3 is also enabled, with laptop mode
enabled and so on, either you are using the cdrom continously (which I doubt)
or your battery is failing imho.
