how to configure pyrit with hybrid GPUs

I have a HP envy m6 laptop with hybrid GPU's ( AMD Radeon HD 7670M and intel integrated) and its a nightmare to get kali to see the ATI chipset it will only see the intel one, ive downloaded all the required drivers and prerequisites for pyrit/Cuda support but the ATI driver will always fail on install as apparently i don't have a ATI card lol . i know how to install pyrit with GPU support as done it many times before with desktops and not run into any serious issues. obviously I've done the normal thing and googled around and looked at many suggestions and forums as you do, but no luck at all. ... not sure its even possible ? out of desperation even tried it on other disto's just in-case was a Kali issue ... and zippo .. closes thing i got was a particular distro (the one you could eat ;-0) it seen the ATI card/installed driver just fine, but still caused issues arriving from the hybrid part
