I was able to get my Sapphire 6850 working today after much work, crashes, and basically stalking every post redshift has in this forum (Thanks Redshift).
Eventually, what got it working for me was making sure I didn't have any conflicting Ati Kexts in S/L/E. Then reinstalling my DSDT using the latest version of Multibeast. Then I set GraphicsEnabler=Yes, AtiConfig=Bulrushes, and AtiPorts=4, and voila it seems to be working great. Fully recognized by the system, dual monitors, and I seem to be getting full hardware acceleration. Though I'm looking for ideas on how to test that.
I'm running a Gigabyte-P67A-UD3 F4 with Lion 7.2 installed.
You're Welcome! Thank you for doing the search and I'm really glad that you were able to work it out for yourself because you will have learned a lot in a short time about hackintosh fault finding!
I thought I was being stalked but then I just realized I'm paranoid!
To test acceleration, just run DVD Player or Chess. If it doesn't crash, your good to go.
For the OP, the DVI-D port does not work OOB with Bulrushes, but the DVI-I port that is on the same slot as the HDMI port does. If it doesn't, then likely you have installed some additional kexts that are conflicting including the ATI patches in Multibeast.
To restate, HDMI, DVI-I, and DP ( although triple monitors will only work if you have 1 Active Display Adaptor ) work OOB with AtiConfig=Bulrushes, AtiPorts = 4 for the Gigabyte 6850C HD 1 GB card. We have proven it time and time and time again. If its not, you have installed a conflicting kext, and need to do a search and read of some of my fault finding posts to correct.
Good Luck! I haven't replied to any more on this as I think all of the answers are included in other posts and help that I've given over the last month or two.
If all else fails, set up a small hd partition, reinstall Lion without any graphics options from Multibeast other than Radeon Monitor, and try it that way with the right config in the org.chameleon.boot.plist file.
