I'm working on an unified serial driver for LCDproc.

It currently supports pic-an-lcd, lcdserializer (a pic-based project,
assembly sources are available) and LoS-panel (currently in
development, with support for backlight switching and keypad, based on
atmel avr, this is the best interface available).

You'll find references to these interfaces, details about the
driver, as well as patches, here:
