Very true.  But sometimes things just can't be optimised any further,
and will always be a hog.  Not saying there isn't room for
improvement, but don't expect miracles.  You can't run a computer with
the CPU off all the time.

Yeah, that's the way to influence people: tell them they're acting like
bureaucratic marketroid idiots.

Well, you've offered your time and help, so all I can say is... please
post patches to bugzilla when they're ready.  I'm not getting a
paycheck working on this stuff, so I work on what I find interesting and
what I care most about.  Eeeking out every possible last kWh from my
laptop's battery isn't #1 on my priority list.
