For this discussion (AMD Opteron), I'd assume a 64 bit program is one that
is compiled to run in the Opterons native 64 bit mode (with the extra
registers).

You don't need to make extensive use of 64 bit datastructures to run faster
on the Opteron in this mode, but obviously it opens up a few interesting
possibilities.
