I am now able to integrate the drivers and control panel into a Vista64 install.

I have only tested this with Vista64.
Here's how I did it.
1: Extract "185.85_desktop_winvista_64bit_english_whql.exe" into a new folder, for example "C:\Nvidia"
2: Click 'Start', 'Run' type 'C:\Nvidia\NvCplSetupEng.exe /a' (without quotes) click 'OK'
3: Click 'Next, enter 'C:\Nvidia' in the network location box then click 'Install' followed by 'Finish'
4: Copy the 5 .chm files from 'C:\Nvidia\windows\help\nvcpl' to 'C:\Nvidia'
5: Copy the 16 files from 'C:\Nvidia\system64' to 'C:\Nvidia'
6: Open 'nv_disp.inf' into notepad and add the following to their relevant section

Create a new section [nv_controlpanel_registerdll]. I put it near the [nv_common_registerdll] section.
