Unfortunately, the top hits for me when searching for "pentium m pae" in
Google is Wikipedia, which is at best misleading if not wrong. And the
second hit is someone asking what processors don't support PAE and
quoting Wikipedia as saying Pentium M is amongst those that don't. (I
haven't linked to those sources in case in helps in some small way to
boost their search rankings.)
I did however not rely on these source anyway and looked at Intel's site
and found the spec for my CPU said it had 32-bit Physical Address
Extensions, which confused me initially because 32-bits didn't seem
'extended'. (I guess it's just that they haven't baked or wired up move
address lines.)
