Hm, not good, as you say, but hid should handle your mouse.
It handles almost everyone else's mouse... unless they choose
to use usbmouse.

A (kernel) config option wouldn't be a good idea for it, but a

could be used to set the option, or the usermap file, like you say,
would also make some sense.
