I just wanted to bring to your attention the ability to use your TFT touchscreen for Arduino (#1651) with the Intel Galileo as a Linux framebuffer. I did a bunch of work to make this possible at: https://communities.intel.com/message/224873#224873. The big difficulty with this is the Galileo’s limited CPU IO. I had to do a bunch of wire soldering and driver changes to re-route the DC and CS pins. Adding the kinds of pads you have for the other Arduinos, except to re-route the pins for Galileo would really help.
