I'm kind of attached to FullScreenReading mode working, so I haven't updated my H2O, but if someone wants to take a look, feel free to take a peek at what nickel is doing w/ eink refreshes:
Code:
strace -fitv -e trace=ioctl -p $(pidof nickel)
(You'll find a strace build handling the mxcfb ioctls in
there).
