I thought 3900 series scanners would share the same chipset class too. That's
why I called my backend "hp3900". As far as I know, Realtek chipset is not
compatible with GLxxx_HP. At least, the way in which each chipset is
programmed is different. Also, ScanJet 4070 uses the same chipset as ScanJet
3970 so, i guess scanners included in 3900 series share some simmilar
features but chipset is not one of them.

In fact, hp3900 backend was written to support ScanJet 3970. Then, other
scanners were added.
