I have listed a step by step procedure at http://prasannakumartsm.wordpress.com/2011/06/28/opengl-3d-and-video-acceleration-in-usb-display-devices-under-linux/ to get OpenGL acceleration using built in GPU. All the applications's OpenGL calls will be forwarded to built in GPU (similar to how it is done in windows for DirectX calls). Off screen buffers are created and all the processing is done by built-in GPU and the resulting image is sent through USB.

This procedure is based on bumblebee (nVidia's optimus technology in Linux using VirtualGL) so this should work. Give it a try and provide results, feedback and suggestions to improve the post. This will not harm your computer but it is better to take a back up of your data before trying as a caution. There were mixed results in bumblebee - some got acceleration, some got partial acceleration it seems. I will soon give it a try once I get a USB display device shipped to me. Thanks to Plugable Technologies (www.plugable.com) for the USB graphics card.
