Ubuntu :: 10.10 - Any Way To Merge Default Graphics Settings?

In ubuntu 10.04 and 10.10 there is now xorg file. Is there some way to merge the default graphic settings with my own xorg file? I'm currently needing to use and xorg file for my via graphics cards, which works fine. However, some functionality is missing. the icons have lost transparency and the unity menu doesn't allow click and drag scrolling anywhere (like a tablet). If I delete the xorg file and run the default, I get all the crisp clear cut of unity but of course I get performance problems everywhere else... i.e I cant plug a multiple screen in and video playback is crap.
