Got an SDRAM breakout board ordered with OSH park today, so at some point I'll try out the SDRAM library (on XS-2, likely). I have an MT48LC16M16A2TG-6A:GTR (256 mbit, 16 bit ifx) to put on it. The "header" holes in this PCB are large because they are designed to allow "deep seating" of special machined socket strips with long pins that extend through the PCB. This allows the PCB to be plugged into a solderless breadboard as well as exposing a set of pin sockets on the top for connecting extra leads or components, allowing it to be used without the breadboard if desired. I'm using Mill-Max part number 311-93-164-41-001000.
Eagle 7.5 files for this breakout board are available in the project files section.
