would suggest to read the screen "OCR" it and make your own screen wth oyr own font and your own info. You could probably do the same with the menus as well, but it would requre some OCR'ing.

You could also trap all button presses and pass on button presses and/or read (as other people have mentioned) from the /proc files.

Look at all the suggestions and combine them and see what you feel is the best solution
