So, if mobility modder has that functionality already, why do you need the ones ATI makes specifically for the laptop GPU? Higher performance? Designed around wattage?
Mobility Modder is not a driver but a program that converts desktop drivers to look like laptop ones. Windows doesn't like drivers that are not specifically set up for the video card you have but underneath, both desktop and laptop drivers are the same (since laptops tend to be underclocked, low power versions of the desktop cards). ATI has graciously "modded" their own desktop drivers to look like laptop ones for Apple. Mobility Modder is not an ATI program, btw, so ATI does not support its use.
