Thank you, Jesse. I will look around the source and check if I can contribute some part.

If you're interested, you can look at the Intel X driver; it should be fairly easy to modify the code to use different refresh rates. See git://anongit.freedesktop.org/git/xorg/driver/xf86-video-intel. Look for "panel_fixed_mode", that'll be what the i830_lvds.c code uses to program the builtin LCD mode.
