CPU Undervolting
I've used phc with the hagan voltages found on : http://www.gentoo-wiki.info/Pentium_M/Undervolting which translate to the following phc vids :
x40 ~ # cat /sys/devices/system/cpu/cpu0/cpufreq/phc_vids 14 12 10 8 6 4 2 0
There is a gentoo overlay by Michael Weber for phc_intel and phctool : http://bugs.gentoo.org/show_bug.cgi?id=283472 (but the original package from http://www.linux-phc.org/forum/viewtopic.php?f=13&t=2 is easy to install)
(exploration notes : the phc kernel patch is included in sys-kernel/zen-sources see also : http://zen-kernel.org/included-code and http://forums.gentoo.org/viewtopic-t-805069.html )
