Is there a way to use this graphic card in Mountain Lion? The MultiBeast 48xx fix doesn't work for me.
 
I'm just trying to do the same thing.

I've manually added the device I'd to the Info.Plist file in the ATI4800Controller.kext (once I realised the info.plist file was hidden), on subsequent restart if has loaded the driver. (for reference I haven't installed the patches in Multibeast, so this is in the OOTB kext file)

my current issue is the Graphics performance is terrible, for instance clicking on Launchpad takes quite a few seconds to eventually paint the screen.

For reference the Information I added was 0x94601002 to the existing string values under IOPCIMatch

Let me know how you get on
