Just very old memories, but wasn't this used with the ability to shift the display ? IIRC the HD44780 has a 2x64 chars buffer and you can make the buffered characters appear when you shift the display. That's akin to seeing the display as an adjustable window over the buffer. I don't remember having used that feature, so if it didn't previously work, please disregard my comment, I just want to be sure we don't break a feature others might be relying on.
