I'm trying to gather information on how this was done, but Endgadget just posted news about this being demo'd at CES. http://www.engadget.com/2011/01/19/amd-announces-fusion-based-embedded-g-series-platform/
With the modding that the community enjoys, and the endless complaints (from myself included) on how closed the hu manufacturers are, something like this would be a welcomed alternative. If there is continued interest in this, I'll continue to post on the information I find.
