It's my understanding that it was Microsoft that was originally behind 
the change from x86-64 to amd64.  I'm guessing that their folks hated 
typing the arch name with the - or _ in it.  Its interesting that their 
most recent release that has 'windows for extended 64 bit systems' 
still has an arch name of amd64 though.  If you extract the hal.dll 
from the cdroot/amd64/hal.dl_ file (see ports/archivers/cabextract)
you'll see that the release does a strcmp for AuthenticAMD *and* 

Actually, I've also wondered privately if the Microsoft angle was also a 
way for them (MS) to get up Intel's nose given Intel's Linux
