	There are alsu a ((very) small) number of ports that do not
compile or do not run in 64-bit mode.  Figure out if one of them is
mission-critical before installing; check for the "NOT_FOR_ARCH" and
"ONLY_FOR_ARCH" settings in the port's Makefile.
	That said, the machine I'm typing on is about six weeks old and
running an AMD Phenom II x4.  I installed amd64 with some
trepidation, fully prepared to re-install i386.  However, it's now
up over 675 ports - including apache, mysql, firefox, and OpenOffice
- and everything works.
