the issue is that "P4" covers a fairly wide-range of hardware, where 
some of the early hardware under the P4 name did not include 64-bit 
support, they enabled it for later cores.

so, it depends on which core it has, for example, a P4 with a Willamette 
or Northwood core will not have 64-bit support, but a P4 with a Prescott 
or Cedar Mill core will have 64-bit support.

granted, an issue with some earlier computers with 64-bit support was 
that, even if the CPU supports it, sometimes the MOBO would not, or 
would not operate reliably in 64-bit mode.


for example, I had a computer with a ClawHammer core running on a MOBO 
using Socket-754 (built around early/mid 2004), and although a plenty 
usable computer, it did not run reliably in 64-bit mode.
