I have eink draw and update code that works on all the eink kindles that I have, in all modes (main and diags). The k4 uses different eink drivers in main and diags mode. I also support full grayscale in the newtrix demo, which dithers 256-shades down to 16, as required even for the 8-bit framebuffers (where the bottom 4 bits must be a copy of the top 4-bits for predictable behavior, according to the eink driver GPL code). My newer stuff (like the video player) does dithering with no dither table and uses ioctl() eink updates. Because it is native code, it might work within your framework.
