To enable native QE graphics output on an ATI graphics adapter, you always need a framebuffer.
  
If anyone is looking for a great setup my rig is now complete and working perfectly! No TEARING! NO ARTIFACTS! Tested in OpenGL window apps and DVD Player etc. Fully Stable. I finally got the patch working by just applying it myself using a hex editor. I am using the 10.4.4 version of the ATIRadeon9700.kext file. I have Sapphire Radeon X800 PCIe 256mb. This is non-pro edition. Note I am running the full resolution of my monitor via the com.apple.boot.plist option file. Device ID is 554F Vendor ID is 1002 of course.

Either a pre-definded framebuffer can be used, or you can patch an existing one to match your graphics adapter's configuration of DVI/HDMI/VGA/Displayport.
Grab a HexEditor from http://www.macupdate.com/info.php/id/17562
+
If you want to apply the patch yourself open your HEX editor and search for 3D 60 5B 00 00 in the 10.4.4 kext file. This simply means the file at /System/Library/Extensions/ATIRadeon9700.kext. (Note however it should work on any version of the .kext 10.4.3-5 so don't fret if you don't have the 10.4.4 one!
+
Be advised that this string occurs in two places. Once you find the two places that this string occurs, replace them with 3D YY XX 00 00 with XX being the first two digits of your Device ID and YY being the second.
+
So for setup it was as follows: 3D 60 5B 00 00 became 3D 4F 55 00 00.
+
Now go into the Info.plist file inside your ATIRadeon9700.kext folder and find the 0x5B601002 line and change it with your device ID like this.
+
For example: 0x5B601002 became 0x554F1002 for my setup. Note that if your card has a different Vendor ID you need to change the 1002 to your Vendor ID as well!
+
I forgot that you need to now make sure are your permissions are correct! Quickly do a:
+
chmod -R 755 /system/library/extensions
+
chown -R root:wheel /system/library/extensions
+
Now reload your kernel extensions cache
+
kextcache -k /system/library/extensions
+
Now try a manual load of your driver before the reboot:
+
kextload /system/library/extensions/ATIRadeon9700.kext
+
  
Reboot and pray to the gods!
+
==Pre-definded Framebuffer==
Good luck and everyone keep up the hard work! If anyone wants to know my setup incase you need a 100% working rig. Here goes:
+
You can choose from the pre-defined framebuffer with [http://www.insanelymac.com/forum/index.php?showtopic=231768 Kaby's edition of the Chameleon boot loader].
  
Pentium D 820 2.8Ghz
+
Example:
Gigabyte I945P-Pro Motherboard
+
AtiConfig=Shrike
Sapphire Radeon X800 PCIe 256mb
+
3Com 3C905B-TX NIC
+
NEC ND-3540A DVD Burner
+
And of course the onboard ICH7 Intel SATA
+
Now if you were able to reboot and wish to change your resolution do the following!
+
Goto /library/preferences/systemconfiguration/com.apple.boot.plist
+
right before the closing line, add the following two lines to look similar to the other lines in the file
+
<key>Graphics Mode</key>
+
<string>WidthxHeightxColourDepth</string>
+
So if my setup was 1280x1024 at 32bit colour, I would add:
+
<string>1280x1024x32</string>
+
  
Hope this helps everyone; If anyone sees anything else that is incomplete let me know.

To enable native QE graphics output on an ATI graphics adapter, you always need a framebuffer.

Either a pre-definded framebuffer can be used, or you can patch an existing one to match your graphics adapter's configuration of DVI/HDMI/VGA/Displayport.

[edit] Pre-definded Framebuffer

You can choose from the pre-defined framebuffer with Kaby's edition of the Chameleon boot loader.

Example:

AtiConfig=Shrike

[edit] Patching Framebuffer

The patching was discovered by bcc9 in this thread. mucha made a guide howto patch.
