If I am running Windows XP or some regular 32-bit Linux

I have a program that uses 64-bit integers heavily, and I would
like it to utilize 64-bit mode in A64, even if this A64 is running
a 32-bit OS.
Is this possible? Or is 32-bit and 64-bit entirely different
"modes" on A64?

They are different modes -- you need an OS that can transition to the
64 bit modes, so that's Windows 64 bit or a 64-bit Linux
distribution, for example.
