Hey, sorry about the outdated kexts but i think by now everyone should have learned how to patch your AMD6000Controller.kext, it is a simple task and there are instructions here how to do it yourself. There is even better way now with Clover, no need for DSDT patches etc, you can do everything with Clover, kext patching, EDID injection etc.
but here it is one last time:
1. Copy AMD6000Controller.kext to your Desktop
2. OPen HexEdit and go to File > Open and chose the AMD6000Controller binary inside the kext
