The update appears to bring support natively for the following GPUs:
ATI Radeon HD 5630 Device ID 0x68D8
ATI Radeon HD 5630 Device ID 0x68D9
ATI Radeon HD 5670 Device ID 0x68D8
ATI Radeon HD 5730 Device ID 0x68D8
ATI Radeon HD 5770 Device ID 0x68B8
ATI Radeon HD 5850 Device ID 0×6899
ATI Radeon HD 5870 Device ID 0×6898
AMD Radeon HD 6850 Device ID 0×6739
AMD Radeon HD 6870 Device ID 0×6738
AMD Radeon HD 6970 Device ID 0×6718
Why would Apple be doing this? Why the support for video cards that aren't optioned in current iMac's? Could it be that Apple might support off the shelf (usually) PC video cards?
This means full QE/CI without Chameleon's GraphicsEnabler or any enabler kexts such as ATY_init." Could this mean the end of the Mac-only graphics card? Could Apple be opening up the platform more? What happens to NVIDIA? Why support for cards that aren't in Macs yet?
