problems & questions with CFAG12864

hello there.

i'm a little bit confused. I've got a CFAG12864BTMIV connected to a MSP430 via a I2C Bus (2x PCF8574). My problem is that i can't get anything out of the display. The I2C Bus works properly (read as well as write)
I've searched in the internet upon other displays with KS108/KS107 chips and i mostly find documents in which the pinning of the data&ctrl bus is as followed :
D/I,R/W,E,DB0-DB7,CS1,CS2,RST
With the CFAG12864BTMIV the pinning is like this (from the pdf document)
DB0-DB7,CS1,CS2,RST,R/W,D/I,E. Altough i use the description from the CFAG12864BTMIV-Document i even can't get the module reset.
Can anybody help ?
