I followed the dual gpu string device id guide by Aquamac to get all three of my gpus recognized. That is two gtx285s and a 9600gso. I had to improvise the in.plist file and add a third child entry by copying the 9600gso template he had. Then I unplugged each card one by one to get the pciroot ids by running that gfxutil command line utility. So it worked and I have dual screen support (one monitor on ea gpu) but if I try to change resolution The screen goes blue until next reboot. I used tonymacs nvidia kext update. Is there a better kext driver package?
