Console/X blanking disregarding setterm and xset options

I'm building a system which supposed to have display always on. But no matter how hard I'm trying to disable DPMS it keeps blanking display after some time of inactivity.
Screen is blanking (and monitor turns off) both in console and X mode (probably they use the same, as my console is FB).

The system is Intel Core i3 based, videocards are intel integrated (i915 module), and Nvidia (nouveau module). Kernel is 3.4.0. Distribution - gentoo.

So far I tried:
setterm -powersave off
setterm -powerdown 0
setterm -blank 0
^^ both options were issued from active console, inserted into bash_profile and in rc.local
setterm -blank poke
^^ installed it into crontab to run evey minute

Under X i tried:
Option "DPMS" "Off" in monitor section in xorg.conf
starting X server with -dpms arg
xset -dpms
xset s off

I'd be glad to disable DPMS completely on driver level, but I dont know how. Any suggestions to prevent my monitor going to sleep?
