This is what I'd expect the cursor just moves to next place and warps
around from end to begining. Display clearing on wrap around may or may
not be configurable.

Take a butchers at the hardware and see if you can work out the
controller ICs number, or any identifying numbers for the module. Though
with five dedicated icons it's quite likley to be a propritary display,
this may make getting a datasheet for it from the web tricky. Try the
computer makers?

Once you have the datasheet it should be fairly easy to "adjust" one of
the existing drivers to talk properly to the display.

I'd look at finding numbers and websearing first, bit easier than real
reverse engineering. B-)
