Why kernel 3.6.2 is so much less energy efficient than 3.6.1 on Mint 13?

http://unix.stackexchange.com – I noticed, that the power consumption in my ASUS P53E notebook is doubled (from 10W to 20W) when I change from kernel 3.6.1 to 3.6.2 (or later). I use Ubuntu Quantal mainline kernel from kernel-ppa/mainline - Kernel Ubuntu on Mint 13 Maya (which is based on Ubuntu Precise 12.04). Please advise me, what additional information I should post, to help you answer. The power measurements agree with the significant difference in processor temperature (ca. 45 C on 10W and ca. 65 C on 20W), so it is not a glitch of the power meter. (HowTos)
