Hi,

I didn't research enough and unfortunately got a Sapphire 6750. Although I managed to get it working at native resolution but I'd really appreciate if you can help also get QE/CI working.

This is the hardware:

• Core i5
  
• Intel DH67BL-B3 Motherboad
  
• Sapphire Raedon HD 6750

ioreg info:

daves-Mac-Pro:~ dave$ ioreg | grep ATY
	| |   |   | +-o ATY,ATY,RadeonFramebuffer@0  <class AtiFbStub, id 0x100000282, registered, matched, active, busy 0 (5154 ms), retain 8>
	| |   |   | | +-o ATY_ATY,RadeonFramebuffer  <class AMDFramebuffer, id 0x10000028f, registered, matched, active, busy 0 (261 ms), retain 16>

With my 5750 I always had to add the device id into the ATI5000 kext.

Edit: got it work fully. Yes, had to add device ID to ATI5000Controller and ALSO AMDAccelerator.kext

Attached are the kexts and boot.plist in case anyone needs it.
