HD66730 Compatibility with LCD Library

Hi all

Does anyone know if the HD66730 LCD controller is compatible with the HD47780 LCD controller? I have a gorgeous 20*4 parallel display (Hantronix HDM20416L-M) with the HD66730, and I am wondering if I can use it with Arduino's default LCD library.

Also, how would you interface a serial LCD display to the Arduino? I have a Crystalfonz CFA-632-NFA RS232/SPI display.
