kde-plasma/plasma-meta includes kde-plasma/powerdevil which seems to be a power management thing that only applies to laptops. Since I'm on a desktop I would like to exclude it. Everything else in plasma-meta seems ok, but it would be messy to put everything but powerdevil in world. I think that powerdevil should be conditional on a suitable power management USE flag. I noticed this because powerdevil hard fails configure, which is a different problem.
Power management, suspend and hibernate are not just laptop related. This is a vital part of Plasma.
