This is a bug that we found too late to change in Leopard GM.

Once again, our sincerest apologies,

I have a somewhat curious difference between the standard command-line

This is on an erase-target-disk clean install of Leopard on a 2nd
generation Macbook Pro.

Okay, finally I got my Leopard DVD and installed it freshly on Core 2
Duo hardware.

$ sysctl hw.cpu64bit_capable
hw.cpu64bit_capable: 1

Then that can only mean you do not have 64-bit capable hardware. Do

$ sysctl hw.cpu64bit_capable

Do you see 1 as the output?
