+The code in LCDproc for the hd4470 LCD controller chips comes from
+"lcdtext" (by Matthias Prinke) or one of the derivatives ("lcdstat4",
+"lcdtime").
+
+You might like to get those packages down as well and have a play.
+
+LCDproc-0.4 only supports 4 line displays, but LCDproc-0.3.5 runs 2 line
+displays also.  A different maintainer is responsible for this version.
+
+The pinouts are like so : (From lcdtext)

+Getting the supply voltage: 
+   Use a floppy supply connector, get it from the game port, take some
+diodes and a capacitor and get it from the port's data lines, get it
+from the keyboard connector or whatever you like. Be save to avoid
+short circuit. You need only 3mA at 5V! (if you have the same type
+lcd)

+Connecting the contrast adjusting pin (Vadj.):
