[Lcdproc] I2C-LCD with 2 enable lines

[Carsten Tschense]

Hi,
I've got a LCD without backlight and 4 rows and I'm using the i2c-driver
on a nslu2.
I connected EN2 to P7, which is usually used for the backlight, but I
was not able to change the driver-code to use all 4 rows :-/
Can anybody help me? =)

By the way, the display gets totally messed up (strange characters) as
soon as I lower the contrast with the potentiometer - the display only
works when the contrast is at maximum - any ideas?

thanks,
Carsten
