Pretty sure that this breaks /etc/rc.d/power_profile
No, it doesn't. I've checked it beforehand. At least in my case variable
was correctly set to C3.
Andiry and I went back and forth on this specific thing quite a bit. If
you note my commit/revert at svn r238004 and r238009 where I did a
similar thing and then had to yank it out.
there's a lot of discussion around this point on the acpi mailing lists.

I knew about that change and its revert. But it was much more invasive,
substituting C-state index with C-state type, that I also consider
incorrect. My change is much more simple. Yes, it may affect some POLA,
but that is all. I wanted to do this for several years, and I believe
that in this case benefits overweight negative side. But if someone tell
I should back it out, I will.
