I certainly understand your skepticism, as I experienced all of the usual issues with various drivers before I ended up with this one. Here is the info listed on the device properties:
Driver Provider: NVIDIA
Driver Date: 12/13/2006
Driver Version: 18.104.22.16852
Digital Signer: Not digitally signed
Under driver details, there is a list of files located in the system32 folder, but none of them have any version numbers attached. I suspect the file names would be the same regardless of the version.
I still have the driver I installed from, if you would like I can send it to you. I did install directly from nvts.inf, and before installing I checked the RotateFlag lines (force of habit), they were already set to 0x40. I didn't alter anything else.
I did install with BIOS v1.8, with the CPU ID table updated to recognize the 2.1ghz Dothan. It was a clean install of Vista Ultimate (OEM), but of course it didn't stay clean for long after going through several drivers ;)
I just double-checked and I am definitely resuming from standby with no issues. I rarely use hibernate, I think it's only happened once on this install because my battery ran low. Even with hibernate, it resumed fine though. The screen and backlight are definitely going off in standby. When I open the lid, the screen is dark for a few seconds, then the backlight comes on, then about a second later the LCD comes on. FWIW, I usually go into and come out of standby by closing/opening the lid, (although I have manually selected standby a few times from the shut down menu and had no problems).
I do not ever connect to an external monitor, so I can't say if that is working correctly.
The only problem I have with this driver is that it won't run Aero Glass consistently. That is to be expected though from a GPU with 32mb of dedicated RAM. There is an old beta Vista driver that will run Aero 100% of the time, but the 3D performance is terrible when running games.
In the BIOS, I have all power saving options disabled, or set to maximum timeout where disabling is not an option. I prefer to let Windows and the Toshiba power app handle all of it. If it would help, I can check what all of my settings are in Vista's power center. I have them all configured manually. The Nvidia PowerMizer options in the Vista power center have messed up names and descriptions, but they still seem to work.
I am planning on formatting my hard drive and doing a clean install of Vista in a week or two when SP1 releases to the public. I will let you know then if any problems start cropping up. That would confirm or eliminate the possibility that there could be left over bits from previous drivers.
