If I implied it I did not mean it I am sorry... (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
