This is generally not a very efficient way of figuring out the root cause of problems and achieving the result you are after. But the both the hardware and this technology as a whole is very new and so I just try to mess around until I get something working and then figure out as much as I can afterwards. Just you know, don't get frustrated and angry with yourself. Nobody seems to fully know how to get it working yet.
I have pasted my xorg.conf below, but I'm not sure if it will help you. I followed the steps in this first post here in the thread very precisely except for the driver download which I took from the wiki link he pasted. I also read that wiki page thouroughly and followed their procedure for removing the old drivers before anything else. Try to make sure you follow the steps correctly. If you're afraid that you have some settings wrong you can back up your files and restart the system installation from start, it doesn't take long on a beast of a machine like this.
I also posted my grub conf, in case you have some settings wrong there. By the way, the dwords part in my xorgs aren't working. I'm trying to get the brightness keys running so I d That way I can make sure it actually works.
And here is my /etc/default/grub:
moth@charm:~$ cat /etc/X11/xorg.confSection "ServerLayout"
Identifier "aticonfig Layout"
Screen 0 "aticonfig-Screen-0" 0 0
Option "VendorName" "ATI Proprietary Driver"
Option "ModelName" "Generic Autodetecting Monitor"
Option "DPMS" "true"
Option "RegistryDwords" "EnableBrightnessControl=1"
Viewport 0 0
moth@charm:~$ cat /etc/default/grub
