An app doesn't necessarily have to require lots of RAM
to benefit from 64bit address space.  For example, a
certain database process might benefit from accessing,
say, 8 GB in its address space, but only actually using
2 GB of physical RAM.  Such a process runs fine on a
machine with 2 or 3 GB RAM, but it has to be a 64bit
system.  It won't run on a 32bit system, even if it had
8 GB RAM or more (accessed via PAE).
