By not offering options that 98% of the users won't understand correctly, w=
e're=20
improving the user experience. (The irony is that pretty much everybody on =
this=20
list belongs to these 98% and at the same time claiming that the options is=
=20
vital. :/) I'd suggest to re-read those references Holger posted. It's not =
like=20
they're written by random people, and it's also not the case that re-iterat=
ing=20
the reasoning in there is efficient, or fun.

I'd suggest that those, who those who disagree with Holger's patch, and thu=
s=20
claim that pretty much everybody who's working on power management at kerne=
l=20
and HAL levels gear up and start collecting data, because unless we can *pr=
ove*=20
that those options make a difference, we should trust our lower level peers=
 and=20
not offer these knobs that hurt more than they do good.

Really, kernel power management is advanced enough these days that we don't=
=20
have to switch CPU frequency manually. And that's a good thing, because it=
=20
*just works*.
