Actually as it happens we do have a precedent too, as here's what I have
just spotted on my laptop by chance when hibernating:

psmouse serio1: synaptics: The touchpad can support a better bus than the too old PS/2 protocol. Make sure MOUSE_PS2_SYNAPTICS_SMBUS and RMI4_SMB are enabled to get a better touchpad experience.

(with a distribution kernel, so clearly whoever packaged that has not
enabled what might be needed). Someone else wanted to be helpful too as
it seems.
