Crippling GPU performance is not a solution and doesn't alleviate pains because
it basically forces me to not do anything 3d-related. I would rather boot with
X disabled so I can force the perf level to high. This is what I used to do and
it's not an acceptable solution.

This sounds a lot like what I've been doing manually which sounds nice. Thanks
for the input. I honestly would like a solution that doesn't cause my machine
to draw an additional 90 watts at idle though. As I said, I've been doing this
for well over a year now and I'd prefer a solution, not a hack, considering how
old this issue is.</pre>
