To install I downloaded the drivers, extracted then edited the following:
ListedDevices.txt add lines for your GPU, in my case
DEV.1080 "NVIDIA GeForce GTX 580"
DEV.1089 "NVIDIA GeForce GTX 580 "
DEV.108B "NVIDIA GeForce GTX 580 "
NvDisp.inf update 3 sections, again adding lines for you GPU
[NVIDIA_SetA_Devices.NTamd64.6.0]
%NVIDIA_DEV.1080% = Section034, PCIVEN_10DE&DEV_1080
%NVIDIA_DEV.1089% = Section004, PCIVEN_10DE&DEV_1089
%NVIDIA_DEV.108B% = Section004, PCIVEN_10DE&DEV_108B
[NVIDIA_SetA_Devices.NTamd64.6.1]
%NVIDIA_DEV.1080% = Section035, PCIVEN_10DE&DEV_1080
%NVIDIA_DEV.1089% = Section015, PCIVEN_10DE&DEV_1089
%NVIDIA_DEV.108B% = Section005, PCIVEN_10DE&DEV_108B
[Strings]
NVIDIA_DEV.1080 = "NVIDIA GeForce GTX 580"
NVIDIA_DEV.1089 = "NVIDIA GeForce GTX 580 "
NVIDIA_DEV.108B = "NVIDIA GeForce GTX 580 "
If you need the info for you particular GPU just grab it from the files in an older driver. No idea how well this will work so try it at your own risk etc.
