Adding 64-bit capability to Pentium M would seem to be more difficult than adding 64-bit capability to Northwood. Why?

Because neither Pentium M nor its chipset (855) support > 32 address bits. P4 has long supported PAE 36-bit addressing in both the CPU and its server chipsets.

Another thing to keep in mind is that without PAE mode support, AMD's hardware anti-virus protection cannot be implemented in 32-bit mode.

In fact, 855PM datasheet says it only supports 2G of memory.
