Check out this post for some info anyway. A lot of good links. I had similar problems. You need to be using graphicsenabler=yes. And the order the framebuffer loads in matters a lot.

It is not just a matter of finding right framebuffer personality. You also need to make sure your card port config is matched with ATI6000Controller.kext.
I think I have the same video card and it works perfectly.
There is other post explaining how it is done:
ATI Sapphire Radeon HD 6870 1GB DDR5 PCIE VIDEO GRAPHICS CARD 100314-3L:
Change system definition to MacPro5,1. You will need to delete AppleTyMCEDriver.kext first, otherwise you will get KP on boot.
Assuming you patched ATI6000Controller.kext to enable all ports on this card:
if you want to go further - you will need to add your card to the AGPM. I just located iMac12,2 default entry for 6xxx series (Vendor1002Device6720) and changed last 4 digits to match my card id (Vendor1002Device6738) and then copy it to MacPro5,1 and changed control-id from 17 to 18 (so it matches macpro control-id). Rebuild caches and my 6870 was successfully recognized on next reboot by AGPM: "[AGPM Controller] build GPUDict by Vendor1002Device6738":
And for very brave ones - you can edit your DSDT to get rid of GE and enable HDMI audio (change PEG0 to correct value for your MB):
