How to turn off screen blanking

[Aryeh Friedman]

I have a kiosk system I am almost done building and the last snag is
attempting to make it so idle time (no keyboard or mouse attached) does not
blank the screen.   I have already tried the following:

vidcontrol -S off
disabling acpi and apmd from the kernel config
enabling dpms via the kernel config and then running xset -dpms

Any other ideas?
