Tried it, but the Kicad version 0.0.020110616-1 (on Ubuntu12.04) says a new
version is required. Looked at the Gerber files. What are the bare minimum
addition required, apart from A10,  to get a blinking LED program going.
Power source & TF socket is enough ?

Everyone is talking about the criticality of DDR layout, the PCBs of
tablets also shows those length matched tracks. Is it only about
terminating the fast signal to avoid reflections or something more than
that in the case of DDR3. There are many references on the web, it looks
like.
