Sorry Andreas, I got the number wrong, but not the specs. The Marvell Vi still only has two 4 lane PCI-e channels.
Further would an 8640D be a better option than a 1.7 GHz 7448? I'm not sure. And no one has touched on the other processors I mentioned.
I'm definitely not that impressed with the 8610. Outside of a netbook, what would we use a processor with a built-in LCD controller for?
Finally, we still have to consider the amount of work involved in the layout of a new board. Unless someone like bplan steps up to do it we are going to need to find someone that's set up to do this kind of work. The only people I personally know make boards for medical monitoring equipment. While they have done stuff similar to this on the side I don't know that I could persuade them to consider it.
Do you have anybody in mind who might be willing to work on this?
