I suggest you to base your design on the i.MX6SL processor http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=i.MX6SL&tid=vanIMX6SL#prettyPhoto
This processor, has EPDC included which will ease up the implementation of an e-Ink display.
There is an evaluation Kit based on this processor that will be of great help:
You will find the Android Source Code and Demo image in the Downloads Tabs.
You can purchase both, the board and the e-ink panel under Buy/Specification.
SabreLite is a 3rd party's board, based on the i.MX6Quad (no epdc included).

Sabre-SDP can be based on i.MX6 Quad or Dual Lite, none of them have EPDC.

Carlos, thank you for the thorough and informative response!
A couple more questions: Would I be able to swap out the SoloLite on the Evaluation kit (EVK) for a DualLite and retain the EPD support?
Does the 'IMXEBOOKDC3-E' include both the EVK and the e-ink screen, or just the screen?
Thanks,
Ali
