10.8.3 - Two graphics cards - [PCI Configuration Begin] - Still booting, with errors #GPU

Hello There…



I am running 10.8.3 with two graphics cards with four monitors (3 monitors on a gt640 and one monitor on a 8600gt) - successfully booting - but with some problems, as you may guess…



First thing I want to say is, while i may get the four outputs from the gt640 only in Windows, I cannot boot properly to 10.8.3 by plugging all four of the monitors to the gt640 only - This makes me add the 8600gt to the hackintosh - which is making the Mission Control and many other animations "lag" and "choppy" - due to the poor performance of the 8600gt



1. Any solutions for booting with only the gt640 with four monitors attached (2xDVI,1xHDMIx1xVGA) ?



And one other problem comes in with the 8600gt, too - it's the very famous [PCI Configuration Begin] Hang… The system is arriving to this line in verbose (-v) boot , no other lines, BUT STILL booting… Things i've tried :



1. boot prompt : "-v npci=0x2000"/"-v npci=0x3000"/"-v npci=0x2000 PCIRootUID=1"/"-v npci=0x3000 PCIRootUID=1" (not at the same boot, of course)



2. replacing the IOPCIFamily.kext and AppleACPIPlatform.kext with the 10.6.7 ones --> This brings me to "Still Waiting for Root Device" !



3. installing EvilIOPCIFamily.kext and EvilAppleACPIPlatform.kext --> As you may think, this leads to the "Still Waiting for Root Device" error



4. replacing the IOPCIFamily.kext with netkas' one (many thanks, but not working) : netkas.org » Awesome



No luck with the spinning wheel on the boot screen… still booting with no arguments at the boot prompt, but without the spinning wheel, meaning the [PCI Configuration Begin] hang…



Any, but any solutions are appreciated…



Thank you all in advance...
