The actual restrictive component is the OS, not the physical architecture underneath. A 32-bit driver will work with a 32-bit operating system, like Vista 32-bit, just fine, even if the architecture is 64-bit capable.
A 32-bit kernel-mode driver will NOT work on a 64-bit operating system, however. The reason for it has to do with backward compatibility and Microsoft's very early decision to allow hardware manufacturers direct access to the OS kernel rather than API's like Apple.
You should be fine shooting tethered with Canon's 32-bit driver on Vista Home 32-bit.
