If I can get a VGA signal from the ATI Rage XL, I can use a cheap LCD controller board to slap on a moderately- sized LCD?

Other details :  Would also like to know if this can be integrated into the system in any way. Not too sure how these embedded systems work so not sure if adding this would benefit the AMD Geode system in any way, or if it is a standalone system. If it is it's own system, maybe have it run something on its own for a dual screen setup

Not worried about batteries at this moment and have plenty of usb joysticks to cut up
