This is really frustrating as if you already have an FPGA (and appropriate regulators), the controller is just redundant overhead (in every metric conceivable).

This is really frustrating as if you already have an FPGA (and appropriate regulators), the controller is just redundant overhead (in every metric conceivable). I'm glad to see at least the beginning of reverse engineering as some of the panels (typically kindle replacement panels) are quite affordable and even the $450 13.3" panel isn't unreasonably expensive. (An FPGA-powered PocketCHIP-like device with e-Ink would be a lot of fun).
