if i understand correctly, you may be looking for xf86MapPciMem(). If you
grep for that inside xfree86/drivers/ati you should have a good starting

xfree86/doc/DESIGN has a description of the structure of the drivers, not sure
if it has everything you need but it should give you something to start off.
It should also be online in xfree86.org and i know there's a pdf version (sorry, 
don't have the links right now.)
