Maybe rename MapperMP8866 to MapperPS2Adapter?

Hmm, actually, based on http://www.linux-usb.org/usb.ids, let's go with
"MapperLakeviewResearch"

Done, though I'm not sure that's the best name either considering that they may
make other controllers with a different button set (e.g. the MP-8800, which
sounds from the name like it has four joysticks instead of two, though I can't
find a picture of it).

   { "0925", "8866", MapperMP8866 }, // WiseGroup MP-8866
   { "0e8f", "0003", MapperXGEAR }, // XFXforce XGEAR PS2 Controller
 };
