I tested RC3 GraphicsEnabler feature with several motherboards/video cards/CPUs/10.5+10.6.
It seems whether Nvidia injection works depends on motherboard ( DeviceTree postion ? ).
When Chameleon reports PciRoot(0x0)/Pci(0x02,0x0)/Pci(0x0,0x0), it always works regardless of OS/CPU/VC.
( Gigabyte GA-MA770-DS3, Asus M4A78 Plus, Asus P5B-E, etc. )
When it repors PciRoot(0x0)/Pci(0x10,0x0)/Pci(0x0,0x0), it doen't. It requires other injectors ( ex. ATY_Init )
( Gigabyte GA-M720-US3 )

I think there is a solution for this problem posted in this thread.

Scroll down to the next to last post - by user BuildSmart. I tried it and it corrected the problem for me.

I actually modified the source as indicated and tested before reporting.
There was no difference.
What's strange ( a little bit ) is that efi string injection by "device-properties" works.

Post your decoded (plist format) device-properties.

Post your decoded (plist format) device-properties.
This is my working device-property.

I modified DSDT.aml/com.apple.Boot.plist and confirmed the fix.
Thanks

Try it with multiple video cards, I think you'll find it doesn't work and if your path is larger than PciRoot(0xN)/Pci(0xN,0xN)/Pci(0xN,0xN) for example like PciRoot(0xN)/Pci(0xN,0xN)/Pci(0xN,0xN)/Pci(0xN,0xN)/Pci(0xN,0xN) and you don't apply the fix listed in the post I left then there is no way it will ever work.
If you have an issue with PciRoot(0xN)/Pci(0xNN,0xN)/Pci(0xN,0xN) then something is reducing the number of bits in pci_addr_t->dev to less than 5 bits (max value of 0x1F) in your case but since I am unable to duplicate your issue I can't verify that a problem exists so it might be something else causing your video issue.
