don't forget to compile it as a module : http://bugs.gentoo.org/202557

cf http://en.gentoo-wiki.com/wiki/TuxOnIce :
select lzo compression in "make menuconfig"
change tuxonice.conf accordingly

I've used phc with the 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 )

Apparently solved with x11-drivers/xf86-video-intel-2.11.0 : http://forums.gentoo.org/viewtopic-t-803621.html
