I hope you are talking about Geode NX. Originally Geode was created by Cyrix and has changed hands few times. It's low power processor but also low performance. Since AMD got Geode, there was number of improvements such as complete implementation of SSI instruction set, clock increase etc. This wasn't quite enough to compete with ARM for example so AMD made their own version which was actually based on Athlon design. With some 6-14W it draws some 3-10x more power of the little Geodes but it also has way higher clock and better architecture. Since it is waay more powerfull, it is perfectly suitable for demanding media applications, something older units couldn't touch. I don't think it is worth to invest time develop low volume hardware of this complexity. I would try picking some of the existing single board computers.
