Nvidia has apparently released a new WHQL-certified Geforce driver, version 186.91. The driver is available for Windows Vista and Windows 7 and dates to September 1st. 

The new driver provides support for all the Geforce cards since Geforce 6 series as well as Nvidia's Quadro, ION and bunch of other Nvidia based IGPs. 

As this one comes via Windows Update, it doesn't include PhysX and 3D Vision with it, but if you want it you can find it over at Guru3D.com.
