I'm not going to explain how to do it, all info is available over net, use google.
4) install drivers pkg for 4800 from #radeonhd channel on irc.osx86.hu (first link in topic)
after installing pkg remove /System/Library/Extensions/Natit.kext
5) reboot, should work just fine
both dvi ports works.
it was tested with standart card (2dvi and 1 svideo ports), nobody tested with nonstandart cards (with vga/hdmi/DP ports)
known problems : vga (with dvi2vga) doesnt work.
