Bug Description
[Impact]
* When using nvidia drivers and the nvidia graphics card is boot vga the intel card will be added twice, causing xserver to fail to start up correctly.
* Proper optimus usecase requires this.
[Test Case]
* Either:
- Have an affected laptop with nvidia drivers
- hack xserver-
# stop lightdm
# echo DIS > /sys/kernel/
# echo ON > /sys/kernel/
* Start xserver with "Xorg" and no configuration file.
* Good behavior: starts normally, with the nvidia card driving all displays
* Bad behavior: "Fatal server error: AddScreen/
[Regression Potential]
* Unlikely to regress, the fix affects code paths that previously were broken, and could have caused devices to be added multiple times, resulting in the fatal server error seen here. Extra checks are added to make sure platform <-> pci device confusion won't happen.
* GPU detection may be affected in some way, testing will have to be done to make sure the normal cases are unaffected.
