I have a Thinkpad T410 with only Intel Graphics (there's another version with nvidia optimus) and i'm trying to get SL to work.
The Vendor ID is 8086 and the Device ID is 0046
Based on manor's post, he used NVIDIA kexts to get his card recognized. I've followed it but it seems quartz extreme in nvidia cards can't be used on Intel ones even with changing IDs. (GeForce.kext, Natit.kext, NVDAN50 or NVDAG100) -->manor.zip
There are also new Apple official kexts for GMA 5700. (AppleIntelHDGraphics.kext and AppleIntelHDGraphicsFB.kext) -->Official.zip
There are MacBook Pros that have this card and Nvidia discrete card and they use an Apple-developed switching system.
I was thinking, if we could use these macbookpros' smbios and use both manor's and official kexts, could we get Snow leopard to switch between the same card by fooling OSX to think that it's nvidia and intel?
Sorry if it's a long post XD
