Of course, but if opteron/athlon64 becomes the main chess platform,
i guess you will ship a x86-64 version (windows64/linux64), a x86-32
(windows,linux) as well a palm version.

If you play a tournament with a concrete hardware, you may even try some
compiler settings for best results on this target hardware :)
