xset and cousins

[cfk]

Gentlemen:
 I have a few embedded systems I am designing that are using fedora. I need to 
have the monitor run all the time. I am currently doing:

xset -dpms
xset s noblank
xset s off

each time I boot one of these systems.

Can someone tell me either which is the appropriate file to put these commands 
into or what a better way might be to ensure the monitor stays on all the 
time.

p.s. I have tried the settings menu in the KDE gui and it doesnt work quite 
right.

p.p.s I would prefer to do this from an xterm rather then a gui.

Charles
