How to disable capacitive buttons (Back + Menu) lights? Which file must be edited?

view story

http://forum.xda-developers.com – Hi there! Please, could anyone help me? I'm using AOKP Milestone 6 and changed original kernel, as the original one is causing problems, but no matters which kernel I use, my capacitive buttons lights keep turning on, even when disabled using options and even when those buttons itself are disabled through CWM. I use navigation bar just like Galaxy Nexus and everytime I touch those buttons or I turn the screen on, their lights turn on also! What I must do here? Which file I need to edit? Thanks so much in advance! (HowTos)
