The intel-drm-next kernel I'm currently running has i915.i915_enable_rc6 set
by default. I can confirm that there's no measurable difference in power
consumption between unity2d and unity3d when idle with this kernel version.

(The baseline power consumption seems to be higher overall for
reasons that I have yet to determine; but that's definitely not tied to
unity or compiz.)
