And what is the difference bewteen a regular pentium processor and a pentium M processor? I know that M stands for mobile, but that's all.
Mobil CPUs are designed to aid in some of the problems with mobil computers: such as heat and battery use. They sense when the computer is running on battery and will actually slow their speed to conserve power (it's a good idea to use your adapter when power is available to allow the computer to run full speed). They will also slow down when they overheat to cool off. The P4 and new Athlons do this too, but the Centrino handles this function better in mobile applications, taking only a small hit on performance, while not getting as hot and having longer battery life.

The real reasons Pentium M CPUs are so power efficient

(Centrino is not a CPU.) Improved clock throttling is not what makes Pentium M CPUs more power efficient than Pentium IV CPUs. This article goes over some of the reasons the Pentium M is so efficient:
