Apple has never made a Mac Pro with Core2Duo processors; they've always used
Xeon multicore systems, all of which have always supported 64-bit applications;
the only Intel systems that ARE NOT supported for 64-bits are the original
CoreDuo Intel iMacs.
You cannot boot the 64-bit KERNEL in the first gen Mac Pros, but 64-bit APPS
will run.
