Do you know if anyone has successfully spoofed a 6950 to 6900? Maybe this is not possible...
Yes it is possible. I helped couple of guys, but on Hacks:

What if we spoof "compatible" rather than "device-id" How should the SSDT look?

would it really be possible on a real mac though?

I sold my cMP5,1 some time ago, but I was using SSDT to inject properties there no problem at all. Apparently though MP7,1 has issues. What gives?
 
Also there is a modified DSDT used to disable NVIDIA GPU on the MP71, which works:

that is a complete DSDT.aml which I wouldn't recommend using on another machine

or something simpler on a hackintosh:

Code:
// save as SSDT-DiscreteSpoof.aml
DefinitionBlock ("", "SSDT", 2, "hack", "spoof", 0)
{
    Method(_SB.PCI0.RP05.PEGP._DSM, 4)
    {
        If (!Arg2) { Return (Buffer() { 0x03 } ) }
        Return (Package()
        {
            "name", Buffer() { "#display" },
            "IOName", "#display",
            "class-code", Buffer() { 0xFF, 0xFF, 0xFF, 0xFF },
            "vendor-id", Buffer() { 0xFF, 0xFF, 0,  0 },
            "device-id", Buffer() { 0xFF, 0xFF, 0, 0 },
        })
    }
}
//EOF

Attached SSDT-AMD6950-V1-6.aml includes both device-id and compatible.
