It's on my todo list.

Won't hurt to try it. If you find any problems, we can fix it up.

Sure. Everything that comes in would need to be saved and checked
against the previous value. If the value changed, write the new value to
screen colored (highlighted??), if not, write the old value without
color.

Sure. Put all the io_reg info in a separate header
(defn/common_megax8.h). Then just #include that header at the right
spot in the device definition. Don't worry about that for now. I'll
handle it once you get the mega48.h code working.

I'm a bit swamped through the weekend with work and getting
avr-libc-1.0.4 released. Do what you can and I'll try to help out some
next week.
