Scatwell,
Research done

. I found out that the display drivers are called ui_xxxx.drv. Basically all the files that start with the ui_ prefix (User Interface) and have the .drv extension are drivers for the display. But there is a flaw in our logic: Lolita's firmware was only for 1.8 inch screens. I'm not sure that they will work on a 2'' screen like yours but you can try and see what happends.
Cheers!
