The file for your wiring is /server/drivers/hd44780-i2c.c.
The information you're searching must be in the function 
lcdstat_HD44780_senddata() of /server/drivers/hd44780-4bit.c. It's the 
enableLines stuff, I guess.
It`s only a little hint (it's all I can do without such a display) but i 
hope it helps.

There's something wrong with the wiring, I guess.
Does the contrast-potentiometer only mess up the display or does it 
control the contrast too?
