Hi!

I do have now a working hd4780 lcd4linux with i2c.
It's kinda working, it becomes corrupted after a while, but I think it's 
something to do with it not being a true hd44780. it's an hd66710, which 
is essentialy compatible but not 100%.

Timings are critical in my platform (PcEngines wrap1c).

I'll help in whichever way you need.
