alright well i can see that working, but i only read the first post which talks about removing the old drivers completely.
It still stands that if you install a default set of amd drivers you'll lose switching. Only HP drivers have that option for some stupid reason.
It's good to know installing over the top works though cuz i have a much newer HP with a 6770m thats switchable. Drivers aren't an issue now, but i'm sure they'll drop support for it by Sunday :P
