Unknown Coprocessor Device (Acer Aspire AX3400G)

(Background: after swapping video cards on an Acer Aspire AX3400G)
An unknown device showed up in the Windows 7 64 bit device manager: Coprocessor.

After some googling.. and going to Acer's website I downloaded the 64 bit drivers.. unrared each into it's own folder and let windows pick through the folders (through the "Update Device" option).

The device identified as "NVIDIA nForce System Management Controller".
The 15.56 nVidia driver might be found here: http://www.nvidia.com/object/nforce-vista-win7-64bit-15.56-driver.html

Hope this helps someone..!

(I'd add a permlink to the Acer drivers, but they keep changing their site around)
(Also works with Windows 8 64bit)
