Has anyone been successful with this card ? If so I should would appreciate the steps that you took and a link to the files that you used. I have tried numerous different ways and still have had no luck in getting this card to work to its full potential. I can get it to work in 10.6.2 if i delete all ati kexts, but will only have 1024 x 768 resolution available.

Boy did I pick the wrong video card.:( 104 views and not one reply with a working card.:'(
Thanks guys, I have tried all suggestions and still black screen.
Here is what is strange about this card. I can log into my desktop with Windows 7 and RealVNC and it shows the correct info for my graphic card and my display. I can go to system preferences and change the resolution and frequency to all available ones that my card supports and it still has a black box on the actually samsung monitor that says "Not Optimum Mode 2048x1152@60Hz" but that is exactly what it is set as. Does anyone have any ideas what the problem might be, I am at the end of my rope on this one and about ready to buy a different card.
I finally gave up :'( and purchased a EVGA GEForce 9800GTX+ and it works with only graphicsenabler=yes.:) Thanks everyone for all your help.

Have you tried PCEFI 10.6 with the graphicsenabler on?
1. Make Sure you have 10.6.2 and have at least Chameleon 2 RC4.
2. Download Kext Utility.
3. Remove ATI4500Controller.kext and ATI4600Controller.kext from System/Library/Extensions.
4. Drag LegacyATI4800Controller.kext (files.net kas.org/10.6.2/LegacyATI4800Controller.kext.tar.bz2) to Extra/Extensions
5. Rebuild caches using Kext Utility.
6. Reboot with -v GraphicsEnabler=Yes and if you get kernel panic in ATIRadeonX2000.kext reboot again with -v GraphicsEnabler=Yes
If this doesn't work (please test all outputs before you assume it doesn't) try installing this (files.net kas.org/QE_CI_Exotic%20patch%2010.6.2.pkg). Then boot again as described in step 6 above.
To use 4850, you need to put correct device ID into Info.plist of Controller & X2000 kext, too
/too slow.
Download mad rau.com/download/latest/latest.html and make your own custom resolution, it worked for 1440x900 when only 1440x1050 was available.
