Using a display module is a more standard solution than trying to hack a
consumer product like a Kindle to do something it wasn't designed for.
The Linux Raspberry Pi projects tend to use userland GPIO "drivers"
written in Python, which are minor effort to port to NetBSD's GPIO API.
They don't give you a native console, framebuffer nor X11 so you
have to develop your own user interface based on their rendering
primitives.
