You need to magically divine what various random windows driver
patches do and also allow for the fact that your i8042 may be completely
faked SMM, partially faked, or just randomly confused. Resetting loses
various bits of config/status that get put back by windows drivers we
don't have enough info on and in machine specific ways.
