Additionally its folly to think servers can't gain from power management.
Most servers are idle, or running maybe 40%, might as well let those other cores sit idle if they aren't used. Example is at idle with power management our latest xeon draws 300W versus 390 without. 900W at full tilt and all power management disabled.
The excuse that windows is a "general purpose" OS doesn't fly in my boat. Granted I don't use Linux for laptops generally but power management should be something any OS does somewhat sanely. We're moving to Amdahls law now away from Moore, also is there a law yet on power requirements for appplications? So power consumption is only going to be more of a basic feature than bolted on. That and doing things like using avx or gpu's for array multiplication because the power requirements are cheaper etc...

Terminal Server running serverside, not clientside, screensaver is poor for performance (https://groups.google.com/forum/?hl=en-GB#!search/windows$20server$20performance$20screensaver/microsoft.public.windows.terminal_services/6i-mfdhLs2g/Qm8wEaEnTL0J https://groups.google.com/forum/?hl=en-GB#!search/windows$20...)
