Indeed, enabling that configuration solves that issue.
However, I think it is quite unintuitive that a module (psmouse) chooses
a default mode which requires another driver which is not necessarily
included; though it would probably be not a very clean solution to
explicitly check that as well.
Is this behaviour, that one module requires another without
communicating that clearly, wanted?
