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. |

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.
