If windows 64 runs, linux 64 will as well; as far as OS are concerned, 
64 bits mode is like a new architecture (like ppc vs intel). When the PC 
starts, the kernel of whatever OS you are running will refuse to run if 
it is 64 bits and you run on a 32 bits machine. The details are OS/Boot 
loader dependent, but most installers will refuse to install a 64 bits 
installers on a 32bits-only machine anyway. You can also run a 64 bits 
VM inside a 32 bits, assuming your CPU is 64 bits capable (so you can 
run 64 bits Ubuntu in vmware on top of 32 bits Ubuntu for example).

I strongly suggest using windows 7 instead of Vista if you can.
