Signs of early radeon 7xxx support in ATI drivers
As you might have heard, Tahiti is a nickname for next amd video cards, probably 79×0.
And guess what, there is some info about it in 10.7.3 beta drivers, in ATIRadeonX3000.kext:

Its a functions names from driver.
So, what is it, just usual early support for future cards, or Apple is testing this card with future Macpro ?
And btw, 6990 works in osx with patched drivers for 6970, just add your dev-id(of master card) into x3000.kext and ati6000Controller.kext’s info plists.

@Peter:
Device ID for the 6990 = 671D.

I only have my 6990 working with the native package method in the article above with GraphicsEnabler=No, so max resolution is 1920×1440 (10MB) and slow.
Would love to see it working, because it’s not that simple.
