[HELP] AMD Radeon HD 6470M

[chardido]

Hi friends,

 

I've a problem with this graphic card. I've installed Snow Leopard 10.6.8 in my Acer Aspire 5253G and all works, but the graphic card not.

 

 

I've tried a lot of guide that allow me to install this graphic card and, in "More Info.." di "About this Mac", i can see this:

AMD Radeon HD 6400M Series:

But, immediatly under my graphic card, there is another monitor:

I've tried to install the last update of Chameleon, and all works fine (my camera also, it didn't work with cdboot), I've tried to edit the .kext, but with no succes (I edit it with info on web).

 

This is an error which the system gave me when i try to run a game:
