It is known to work on the Nook Simple Touch, which uses similar hardware. The NST project may be a good starting point for a kindle port.
If you could get the USB host stack working on your microcontroller so it can act as a host PC, it would be fairly trivial to connect to the kindle using the USB serial gadget, with no need to wait for USB OTG on the kindle.
You can also remote-control your kindle over wifi, so no USB cable needed.
Or, if the goal is a "bathtub ereader", put your kindle in a ziplock bag and press the buttons through the plastic.
