powerd doesn't decrease CPU frequency in some cases

I agree my patch isn't ideal.  I was thinking about it today and it might
be useful to implement something that ignores frequencies whose power
ratings don't differ by more than X mW.  In my case, both 2201 and 2200 are
rated to draw 35000 mW.  The question is, in these cases which one of the
two should be ignored?  Can't ignore both...

Sorry Andrey, I missed your patch.  Was a bit overly excited when I saw
someone else finally experiencing the same problem as me after receiving
zero response a month ago when I posted about it. :)

Something I asked in my post a month ago was where does
dev.cpu.X.freq_levels get its data?  I was thinking it might be something
that can be addressed with a patched ACPI DSDT?
