Asus UL80VT
BenQ Joybook S42
Dell Alienware M11x

If you have a Hybrid Graphics notebook that is not on the models list above please let me know so I can add it to future releases.
Driver Signing & Test Mode for Unofficial 64bit Drivers
1.)Download Driver Signature Enforcement Overrider
2.)Disable UAC (Can usually be done by typing MSCONFIG in run and going to the Tools tab. You can re-enable it after installing the same way.)
3.)Run the Driver Signature Enforcement Overrider and choose "enable test mode"
4.)Reboot. (You should see Test Mode at the bottom right corner after reboot.)
5.)Run the Driver Signature Enforcement Overrider again and choose "Sign a System File"
6.)In the box type "C:\Windows\System32\drivers\nvlddmkm.sys" and click ok (do not include the quotes.)
7.)Click "Sign a System File" again and this time put "C:\Windows\System32\drivers\igdkmd64.sys" (do not include the quotes.)
8.)Reboot and all should work.
Special notes for the old Sony Vaio Z (VGN-Z model):
If you get a screen that looks like this you need to update your bios.
Sony Vaio Z (VGN-Z Model ONLY) - LOWEST BIOS version for proper graphics functionality (by model):
Z590/Z2 Series and lower models = R2170M3
Z690/Z3 Series and newer models = R4043M3

Update: 6/24/10 - Found a couple of cool new feature(s). New Hybrid Graphics Notebooks. New Drivers.
Nvidia has finally added a feature to their hybrid power taskbar application that allows for easier whitelisting and blacklisting of programs. This will allow you to unlock programs that may be blocking switching without having to quit them first.
Always on the lookout for new Hybrid Graphics (aka Switchable Graphics) notebooks. I have recently stumbled upon new notebooks from Lenovo and Asus that feature the new generation of Hybrid Graphics (with Intel HD) like the VPCZ11/12 Vaio Zs.
The new 256 series of drivers seems to have introduced a new set of issues with Hybrid Graphics notebooks. 258.49 seems to be the only one thus far that seems to function semi-correctly. (I haven't tested 258.19 yet) I have posted a Nvidia 258.49 / Intel 1994 64bit package for testing but am already working on revisions to it. The package does not include the new features or notebooks and I need more testing on Hybrid Graphics notebooks other than the (VGNZ) Vaio Z.
Reported Issues:
Sony Vaio Z (Z11/12) - Still can not get the newer drivers working on the Z11/12. This is due to issues with the newer Intel drivers properly outputting to the notebook screen. Until we can get this fixed we are stuck at 1994 which does not support Intel HD in the Vaio Z and newer Hybrid Graphics notebooks.
Sony Vaio Z (VGN-Z) - Random screen flashes. (This is caused by powermizer, disabling powermizer fixes it but there is more heat & fan noise.)
BenQ S42 - the nvidia device does not disappear from device manager after being switched to intel. May not be powering down the Nvidia part correctly for S42.
Acer Aspire 5935G - Nvidia device does not disable. Similar to BenQ. Hotkey Switch does not work. Brightness adjustment not working.
Asus M11xR1 - Nvidia device does not disable. Similar to BenQ.
Asus UL3/5/80VT - Nvidia device does not disable. Similar to BenQ.
