Laptop 'video driver chip' input signal EXPLOITATION!

So, my laptop the Dell latitude xPi ps100 or whatever it is, has a 'Neo-magic' video/graphics chip. My impression of the purpose of this chip is to output the video signal, probably digitally, to the LCD. (To do this it, naturally, requires a driver... a piece of software that the computer loads which allows communication between itself (the computer) and the video chip.)

My question is, where does the video signal come from that goes INTO this mysterious 'video chip?'

My thinking: perhaps after the computer starts up and loads the driver for the chip (to get the LCD monitor working), the input signal could be 'hijacked'... replace by a video signal of my... OUR... choice. Related, and implicit question: what 'format' is this input video signal?
