not only nvinject, but by rm -rf all the NV* includes "nvinject, nvdaresman, nvdanv50hal etc.." all kexts related to Nvidia plus the other one is for Geforce "Ge*"

Ok, got my 6800GS fully working. I installed the latest NVinject, then I proceeded to install Zephs Universal NVidia Installer, clicked only the new kexts, not the NVinject in the installer (note - I installed the latest NVinject already via terminal) then when it was all installed I went in the extensions folder added my dev id to the info.plist files, repaired permissions etc.. rebooted, applied the cpuid-graphics patcher, rebooted and boom! Everything works!!!
