SVGALib probably and that should be it all.

Well, should it support both mice and tablets, and preferably other
devices using the event interface, it'll be a little more than just a
few hours.

Sure, it's attached. However, it works for mice only, it doesn't fully
replace mousedev.c functionality - mousedev is able to take input from
digitizers as well.
Btw, should you be interested in testing it with non-USB hardware, no
problem, I have patches that send input from other devices (PS/2 mice,
keyboards, and more) through the same interface. (see
