family 15 model 2 is northwood based. no amd64. the best option for that 
one is to find a cheap second hand box with a CPU that's only 10 years 
old instead of (literally) 20 years old and retire it; those old p4's 
were really power hungry, and it shouldn't be hard to find a replacement 
for a cost (maybe even free) that will pay for itself in electricity 
savings alone.
