Is Hitachi hd66717 compatible with LiquidCrystal?

The docs say that it "works with Hitachi HD44780 (or a compatible) chipset". Does anyone know if the Hitachi hd66717 chipset is "compatible"?

BetterSense:

I took a quick look at the datasheet for the HD66717 and it does not look at all compatible. That being said, there are some similarities in the instruction set and they probably derive from the same source.
