Instead of the RD4247MAG3110, I would steer you to the Freescale Freedom boards (KL25Z, KL26Z, KL46Z or K64F) plus sensor shield. You can find all of these at http://www.freescale.com/freedom. The Freescale Sensor Fusion Toolbox for Kinetis supports these "out-of-the-box". The RD4247MAG3110 demo that you've probably seen runs the magnetic calibration code on the PC-side, where-as the Sensor Fusion Toolbox runs it on the Kinetis MCU. Freescale has deprecated the original magnetic calibration library in favor of the Sensor Fusion Toolbox version. The latter is directly derived from the former, but is more up to date.
BTW, the MIG repository IS the same code as that in the Sensor Fusion Toolbox. However the MIG version does not include the MQX RTOS wrapper (which is subject to different licensing).
