Committed to CVS.
Thanks.

I guess the problems stem from the somewhat misleading documentation.
What do you think about changing it from

 Name  Pin   Name
  ...
  D5    7     RW   5 (LCD3 - 6) (optional - pull all LCD RW low (*) )
  D6    8     EN   6
  D7    9     EN2  (LCD2 - 6) (optional)

to 

 Name  Pin   Name
  ...
  -     -     RW   5  (set to GND if not used otherwise)
  D6    8     EN   6
  D7    9     EN2  6  (optional: EN line for 2nd display)
  D5    7     EN3  6  (optional: EN line for 3rd display)

Do you think this is better ?

Peter
