Perhaps a "mouse" line discipline?  It could accept an ioctl to set
which protocol (Mouse-Systems, or MS-Mouse) and send up some standard
protocol to the reader.

As for choosing a standard protocol for the topside, I like the SunOS
"firm event" protocol, which can encode several types of events, and
offers the actual time the event occurred (often useful to have).
