Research the power requirements of said CPUs as well as the P4 tends to be a desktop replacement...

The Pentium M runs at much lower clock speeds, 1.0 mhz to 2 mhz instead of 2.4 mhz to 3.2 mhz for the Pentium 4 and Pentium 4m.

This allows a thinner case as a smaller heat sink and/or fan is required to cool the system.

High performance desktop video cards require much more cooling also so that is why you see only 32mb, 64mb and now 128mb ATI or Nvidia dedicated video cards in laptops.

The Toshiba M30/M35 series and the Compaq X1000/HPZT3000 series were specifically designed for the Pentium M (Centrino) architecture so they are much thinner and weigh 6.2 pounds and 6.5 pounds respectively.

The older Dell Inspirion models, even though they have a Pentium M, were not specifically designed for the Pentium M so their cases are thicker and heavier. However, the Dell D800 is a new lighter design that reflects the Pentium M but it is more expensive (see Cnet review).

Note both the Toshiba and Compaq/HP above have 15.4" widescreens so their low 6 pound weight is very good. If you get a 14.1" screen from IBM with similar components the weight will drop into the low 5 pound range.

You can go even smaller and lighter of course with Sony and Fujitsu but once the screen is smaller than 14.1" it is limiting for normal work and would be more for the frequent traveler.
