By not offering options that 98% of the users won't understand correctly, we're 
improving the user experience. (The irony is that pretty much everybody on this 
list belongs to these 98% and at the same time claiming that the options is 
vital. :/) I'd suggest to re-read those references Holger posted. It's not like 
they're written by random people, and it's also not the case that re-iterating 
the reasoning in there is efficient, or fun.

I'd suggest that those, who those who disagree with Holger's patch, and thus 
claim that pretty much everybody who's working on power management at kernel 
and HAL levels gear up and start collecting data, because unless we can *prove* 
that those options make a difference, we should trust our lower level peers and 
not offer these knobs that hurt more than they do good.

Really, kernel power management is advanced enough these days that we don't 
have to switch CPU frequency manually. And that's a good thing, because it 
*just works*.
