Hi there, I recently have bought a XFX 6870 GPU for my Mac Pro 1,1. I've installed this http://www.groths.org/?p=431 Problem is that my displays are not detected in OSX. (See attached image). I've tried different ports and displays with no luck. I only could get this image with a remote desktop. If I boot in windows, there's no problem, just OSX. I've been reading and reading and haven't been able to find a solution for this issue. My last hope is that someone here can help me, that would be awesome. Thanks!
