Firstly, let's look at NV40's device IDs:
NVIDIA_NV40.DEV_0040.1 = "NVIDIA GeForce 6800 Ultra"
NVIDIA_NV40.DEV_0041.1 = "NVIDIA GeForce 6800"
NVIDIA_NV40.DEV_0042.1 = "NVIDIA GeForce 6800 LE"
NVIDIA_NV40.DEV_0045.1 = "NVIDIA GeForce 6800 GT"
we can see that DEV_0040.1 is the 6800 Ultra, the DEV_0041.1 is the plain 6800.
Secondly, let's look at some NV35's device IDs:
NVIDIA_NV35.DEV_0330.1 = "NVIDIA GeForce FX 5900 Ultra"
NVIDIA_NV35.DEV_0331.1 = "NVIDIA GeForce FX 5900"
NVIDIA_NV35.DEV_0332.1 = "NVIDIA GeForce FX 5900XT"
NVIDIA_NV35.DEV_0333.1 = "NVIDIA GeForce FX 5950 Ultra"
NVIDIA_NV35.DEV_0334.1 = "NVIDIA GeForce FX 5900ZT"
we can see that DEV_0330.1 is the 5900 Ultra, the DEV_0331.1 is the plain 5900.
Then, let's look at the 7800 GTX's device ID:
NVIDIA_G70.DEV_0091.1 = "NVIDIA GeForce 7800 GTX"
It's DEV_0091.1
Following by 2 previous generation's device id order, this is the PLAIN version of G70 series!
