Advice - don't try and just bolt on a mouse with a hack. reality is to do a mouse, you're doing sprites/overlays and/or compositing (to do it right) so instead of bolting it on with a hack, bite the bullet and work out how to do some proper compositing of images (sprites) off-screen with also retained off-screen content of the screen then transfer any changes on to the screen when done.
Actually, raw fbdev isn't the right choice for such things - unless one really hasn't any other choice. DRM has support for such things, easy to use via libdrm: https://github.com/metux/twtk/blob/master/src/platform/drm.c I'd also recommend using some existing library for drawing (eg. cairo).
