You can save some battery power by decreasing the cpu core voltage. linux-phc.org provides an kernel interface to these voltages via a patches acpi-cpufreq module, called phc-intel. This is the ebuild for the latest intel release. Instead of http://bugs.gentoo.org/show_bug.cgi?id=158579 this ebuild uses the supplied Makefile and prepare.sh for the kernel-module patching. CONFIG_X86_ACPI_CPUFREQ must not be Y (compiled in). I've added this to my overlay at http://svn.xmw.de/gentoo-overlay/ Reproducible: Always

i would suggest that it is moved to sys-power as it is also applicable for all intel cpus
Created attachment 203437 [details] inherits from linux-mod A slightly different approach: it inherits from linux-mod which simplifies things a bit: linux-mod does installation (instead of doing a make install) and as a result patching for sandbox violations is not required. Also linux-mod runs depmod in the end so that the user doesn't have to do that manually.

Seems a quite interesting package If someone is willing to proxy-maintain it please let me know. I can commit this ebuild for you on portage tree
These Ebuilds were now in sunrise overlay http://overlays.gentoo.org/proj/sunrise/browser/reviewed/ and in the main tree, tomorrow. \o/ Michael
