The Centrino brand refers to a combination of Pentium M, Intel chipset
and approved WLAN adapter which all have good power-saving facilities.
It doesn't refer to a processor.

You are correct that most Pentium M processors do not have PAE (or do
not advertise it in CPU feature flags).  I didn't know some of the
Pentium Ms were also called 'Celeron'; I'll see if I can rephrase the
description accordingly.
