PAE kernels can access up to 64GB of memory, though any individual
process can "see" only 2GB (IIRC).

But even in the original described approach (32-bit apps on 64-bit
kernel), because the apps are 32-bit, that will only be able to address
2GB anyway. If you have apps that need access to more RAM than that, you
should be running 64-bit apps, not 32-bit.
