That's the odd thing; PAE has been there since the Pentium Pro, so the P3 had it. It seems that all x86 processors since the PPro, except for the 400MHz FSB Pentium M's, have PAE.
Oddly, the 2.0GHz Dothan is documented as having PAE; it's only the 400MHz FSB (Banias) ones that are documented as having PAE disabled. The PAE feature apparently affects more than just the address space, at least according to the Pentium M Wikipedia article.
