Why is it odd?!?
The ability to run legacy 32-bit x86 binaries under a 64-bit OS at
full-speed is one of the huge capabilities AMD brought with this
architecture. Unless a binary does 64-bit math or addresses >4GB of
memory why does something need to be 64-bit???
The fact that all Open Source OS's have a 64-bit userland on all their
64-bit platforms that grew up from 32-bit CPU's shows how unsophisticated
our build framework is. "64-bit" Solaris today is really a 64-bit kernel
and mostly 32-bit userland.

Nope, it has been a 32-bit 'i386' binary since the day the port started
supporting FreeBSD/AMD64.
