A few years ago I and another OM (F1VL) we remade a firmware for this, the code is here:
The code (Inc/board_config.h) indicates that the display is driven by an ILI9320 and an ADS7843 for the touch controller.
The code can run on an alternate hardare configuration using a 2.4" display controlled by an ILI9341
Hope this helps
