I'm back
I tried different drivers and injectors, but I only get QE/CI working by adding the DeviceID to ATIRadeonX1000.kext/Info.plist. I had to remove ATINDRV.kext and ATIRNDRV.kext, because when I leave them installed I can' use internal nor external displays. I've noticed you guys working on several ATI related driver projects. Could you PLEASE help me?
And, YES, I still use that old and crappy graphics card:
ATI Mobility Radeon X1300
