There are no single 32 and 64-bit versions. Debian has different ports
for different architectures which are either 32 or 64-bit. You (as many
people) are confusing "32-bit" with x86-32 (i386 port) and "64-bit" with
x86-64 (amd64 port). But there are 32 and 64-bit non-x86 architectures
out there, and Debian supports some of them too.

No, this is wrong.

PAE is a 32-bit feature. Most 32-bit-only x86 processors starting from
Pentium Pro (including Pentium II/III/4 and Athlon) support PAE.

An amd64 OS won't work on an x86-32 CPU with PAE support.
