ATI Radeon HD6850 not being recognized

[joeche]

Hello all!
I can not boot without GraphicsEnabler=No

I was able to install 10.7.4 by cloning my other Hackintosh. I have been able to get the network card to work but it seems like all the instructions I've followed don't fix the graphics card issue, so this post is out of a month of frustration. Any help or ideas are appreciated.

What I have:
Gigabyte GA-Z68XP-UD3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard

GIGABYTE ATI Radeon HD6850 1GB DDR5 2DVI/HDMI/DisplayPort PCI-Express Video Card GV-R685OC-1GD
Intel Core i7-2600K Quad-Core Processor 3.4 Ghz 8 MB Cache LGA 1155 - BX80623I72600K
Corsair Vengeance Blue 16 GB DDR3 SDRAM Dual Channel Memory Kit CMZ16GX3M4A1600C9B

If I boot with GraphicsEnabler=No, I can always get in, but the Display option is always 1024 X 768

Here is what the system profiler shows:
Display:

Type: GPU
Bus: PCIe
PCIe Lane Width: x8
VRAM (Total): 3 MB
Vendor: ATI (0x1002)
Device ID: 0x6739

I have also tried the following based on other forum posts but it didn't seem to help.

I also tried installing the following using KextBeast, based on another forum post, but that didn't seem to help.
AMDRadeonAccelerator.kext
AMDRadeonVADriver.bundle
AMDRadeonX3000GLDriver.bundle
ATI6000Controller.kext
ATIFramebuffer.kext
ATISupport.kext
lspcidrv.kext

I've tried putting the card into the other PCI slot, didn't help.

I tried a clean install from mountain lion. It didn't help

I built an exact replica of this machine before and everything was great. So I ordered the same parts.
I tried cloning from the replica machine that everything was working on. It didn't help.

If ANYONE knows what I should try next, it would be greatly appreciated!

Have you tried without modifying the kext?
Like:
Put the USB in boot into it and start the installation with "GraphicsEnabler=No" and proceed the installation as normal and then after the installation boot into the USB and once again the Graphicsenabler and when you booted into the multibeast installation + combo update 10.8.2 http://support.apple.com/kb/DL1581 and then restart?

If it doesn't work do the same thing again but delete the ATI6000CONTROLER.kext from your unibeast USB. if you can't find it; get Show Hidden Files for Mac and go into the unibeast USB System/libraries/extensions and delete it there and empty the trash bin.

That's what I had to do to get my 6850 to work properly
