It is normal, if you are trying to climb the hill without losing speed, which is what cruise control is trying to do. It is flooring the pedal until it regains the lost speed. If it can't maintain the speed that way, cruise will drop out, and you will have to do your own driving.
Your car will do the same thing on grades, in cruise. But your car may have enough excess power that it does not need full throttle, for as a long a time, to regain lost speed on a grade.
Running at 5400 RPM, even all day, will not hurt that engine, but it will use a lot more gas than a more reasonable approach to the hill. I prefer to tackle grades with my motorhome at a speed I can maintain in a gear that lets me run 3000-4000 RPM.
