OK, Install these kexts wirh Kext utility in S/L/E, what's your vendor/device ID ? Mines are 0x68f91002 and that's the ones used in those Kexts. If yours are differents, you may have to edit info.plist for AMD5000Controller.kext and AMDRadeonX3000.kext (in IOKit Personnalities under AMDCedarGraphicsAccelerator and IOPCIMatch) to make it works. Also If everything is OK, you no longuer needs GraphicsEnabler=Yes and Eulemur FrameBuffer in Chameleon.Boot.plist. Don't forget to rebuild permissions in S/L/E after installation but Kext Utility should do it automatically.
Enjoy Full QE/CI ! Good luck !Go to the full post
