it's a character device, you can probably use a standard tty driver, and customise a tad.

Oh yeah, just a tad :-)
Don't know the board - whats the interface to the LCD? Is it a parallel interface?
Is the board HD44780 compatible, if so there is loads of example code out there for driving these boards - do a google search. You may be able to do a userspace program.
If you write a userspace daemon that is accessed by other programs via a named pipe you have a lazypersons driver of sorts.
have
the
and
if it has serial interface capabilities then it'll probably be a breeze to use the tty driver, if it's a parallel lcd it's a little more complicated. you can pester the guys at lcdproc for info, but there's a bunch of parallel lcd's with serial modes, so the list of lcd's you wouldn't be able to use the standard tty drivers on are more manageable.

If it's an standard rs232 interface then it should be a no-brainer, and you should be able to just do everything in user space.
