I had a quick look at the controller's datasheet today. I have already seen those DOG modules in german stores. The controller is interesting because of his 3-line mode. In 1-line mode DDRAM is addressed linear (like in lcdproc's ext_mode). In 2-line mode the address of the second line starting at 0x40 (like in lcdproc's hd44780 standard mode).
Did you had a look at the character table? I have not checked if it matches an existing one, but as it supports umlauts as well as japanese characters.
