I think the geode+ddr that you are referring to is the AMD Geode GX2. It's being sold in India (typically together with broadband packages) as the basis for a low cost computer called the AMD PIC. It's priced at USD$185 without a monitor and has DDR330 128MB RAM, 10GB hdd, audio, 1024x768x32@75Hz video. It's a 400MHz part, the GX533 label, I think comes from it's "equivalent performance" measurement.
and no ethernet, sigh.
