Hmmm, it looks alright.
The driver gets loaded and the server screen is being rendered.
On shutdown the "Goodbye"-Scrren is being rendered too.

So, from this point of view everything looks very promising.

I guess you still do not get anything displayed on the display, do you ?
If you don't, I am a bit lost (not knowning the hardware).
Possible causes where I'd start looking
- hardware: is the board O.K.; are the chips on it O.K,
what about the variable resistor ? Did you play around with it ?
- software: the low level functions of the driver (writecommand, ...)
might not be O.K
Maybe you can instrument them and find out how they
should behave

Hope it helps
