Level of understanding the problem at hand ...

Go read a bunch of "booklets" for different video cards, then read a
couble of books on PC video hw, and then come back with a better
understanding of the problem(s).
Then tell me again how easy it will be to make this work on ALL
video hw....

PS: If you don't have any PC hw books handy, look at the XFree86
    sources for the video hw they support.
