Hey Ben.
I recently saw a new product marketed from Gigibyte, the Booktop M2432. It features a docking station which allows the notebook to use a desktop graphics card when attached, and use the low power notebook GPU when not attached. I wonder if you (meaning YOU, Ben Heckendorn) could some how do this without buying the product. If you could also show us how to do it, that would be a plus as well.
The website for the product is http://www.gigabyte.com/press-center/news-page.aspx?nid=1034
All hail, Ben Heckendorn, King of Engineers!
