Radeon HD 6670 shuts off on login screen after upd to 10.7.2

[Martytoof]

Gigabyte Radeon HD 6670
Chimera 1.5.4
MacOS X 10.7.2

After upgrading to 10.7.2 my video dies as soon as MacOS tries to go to the graphical login screen. ATIPorts 3 is set in my org.chameleon.boot.plist.

This was working fine before the install so I have to assume there is some incompatibility.

Setting GraphicsEnabler to NO in my boot.plist lets me boot graphically, with full resolution but I have no framebuffer loaded (obviously).

Same issue here, except that I upgraded to 10.7.2 first, then went to Chimera 1.5.4 to try and enable iCloud access.

GE=NO allowed me to access the system and confirm that iCloud was indeed working, but I would love to not have to do that permanently.

Same exact issues here.

I am having the same issue, but reverting to chimera 1.4 using multibeast 3.8 I don't have the issue. Is there any real advantage of using chimera 1.5.4?

I was on Chimera 1.4.x, and 10.7.2 with no problems. Upgraded to Chimera 1.5.x and the DVI port has no out put on reboot. I had to put PCIRootUID=0 at the Chimera screen to get out put from DVI.

Same here, Radeon 6870, Chimera 1.6.0.

Everything's great up until the login screen step, then "No input signal".
GraphicsEnabler=no "works", but nothing shows up in bdmesg then.

Any ideas?

Same here, Radeon 6870, Chimera 1.6.0.

Here's my bdmesg:

Update: I switched to the Bulrushes framebuffer and everything's working fine now. Cinebench 47 fps.
