AMD 6XXX Support lost in Dev. 3

[-BigMac-]

Hi guys.
I had the 6950 working unmodded on dev.1 and dev 2. apart from the boot loading screen, everything worked flawlessly.

Since upgrading to dev. 3 of 10.8 i cant even boot with the card. Nothing shows up, at all. Had to switch back to the 5770

Are others experiencing this also?
Running via dual link dvi to 30" dell u3011.

Thanks for your help

Last I checked, you were the only one having it working on dev 1 and dev 2 in the first place!

search google for 6950 10.8. theres manymany posts about it, including huge techsites explaining 6950 AND 6970 work on 10.8 without modding. I am not the only one. Maybe the only one on this site to write about it, but there isother sites than Macrumors that have reported its compatibility

Flashed 6950/70 cards worked great in 10.8 DP1. The issues started in later versions. In short, it seemed that the support got intentionally borked after they read these posts here and at Netkas.
