with the files naaquada provided, I get full QE/CI but no resolution switching. that's with *and* without ATIinject. also, there's incredible mouse tearing when scrolling, clicking etc.

EDIT: turns out that I do need ATIinject. for some reason I had atiinject and natitx1600 installed both (they seem to be the same thing). without atiinject, natitx1600 will take over, but it seems to fail more often.

EDIT2: with graphics mode specified in com.apple.Boot.plist, I get 1280*1024 and QE/CI. still mouse tearing, but I can live with that.
