I've now updated my regular laptops to HEAD after this commit and have discovered that the power consumption seems to have increased significantly. This is on a Thinkpad X220 (Sandy Bridge). It has a r286085 kernel installed on the disk, and reports 11W while idle at a vt(4) console without the driver loaded. After loading i915kms.ko but still at the vt(4) console that increased to 14W. Booting from a USB stick at r296565 showed 13W initially, rising to 25W after loading i915kms.ko. I'll continue to investigate, but would like to know what others observe with respect to power consumption on other laptops.
