Take a look at my fork of BeRTOS. I've put together an i2c display interface
and a 'terminal emulator' that allows you to stream data, including cursor
controls, and that also maintains a screen image so that the text can be
read back (I use it to mirror a display to a remote).
You'll want the 'all' branch and take a look in the bertos/drv directory
at term.c and lcd_hd44780.c
