Can't find a kext for my GPU...

I have an Asus laptop e350 model (it's AMD, but I already found kernels for it so it isn't an issue). But I can't find a kext for the Graphics (ATI Radeon 6310 Mobile). For a better resolution, should I find a similar kext, edit a kext, or somehow force my system into using a higher resolution?

Also, I can't boot up without GE=N

What am I missing? Is it really as easy as the steps outlined above? Please comment to help me do this right guys!
