Atkbd should be able to load automatically (as long as modutils support SERIO bus, which any recentish - 5 years? - modutils should do). libps2 should load automatically to resolve dependencies of atkbd/psmouse. i8042 is old-style platform driver, so nothing will load it if it is compiled as a module. This one worries me most. mousedev should load automatically if something tries to open it's device nodes.
