nvwgf2um.dll causes a full APPCRASH condition loading any webpage in IE9 final

Just installed the new full release of IE9. Leaving GPU acceleration turned on  results in the following error for every page I load:

The culprit has to be the Nvidia Optimus GPU in this Lenovo T510. This is one of those hybrid GPUs that can switch between the Intel HD integrated graphics adapter and the discrete Nvidia unit. Even if I use the Nvidia Control Panel to specify that I want IE9 to use the discrete graphics adapter all the time, it still crashes. 

If I turn off hardware acceleration (ie using software rendering) in IE9, then the crashes go away. It does not matter what website I load, it seems to crash every time.
