hmm?? i don't understand why can't you update your drivers for the mobility chip. it uses the same graphics processor, except that its been "under"clocked to save battery power (hence the "go" part, but granted, its still the best mobile GPU).
as far as my understanding goes, you should be able to use the same drivers as a standard radeon card (thus, you should be able to use the 5.2 catalyst drivers). now, if your refering to the catalyst control center, then yes, i can understand where you're coming from. but, thats an optional part, especially since you need the .NET framework installed.
See the struggle of the faithless lot as they negate their time
How low to sink to the depths of their frame of mind
