(bad example) there are other ports that do work with PAE and not with AMD64 (forget what they are right now since I switched from amd64 to i386 almost 6 months ago)... also I do not know of any ports that do work with amd64 that do not work with PAE... I have not checked this but I think the primary difference is how large gcc reports void * (and other ptr's) to be as well the size of int's
