Yes. (If you don't want PAE. You probably don't.)

Yes, it works fine on AMD64 and intel EM64T processors.
By the way, using 64bit (FreeBSD/amd64) can even be useful
if you have less than 4 GByte RAM. For example if 32bit
address space is not enough for your applications. In this
case, not even PAE can help -- you _have_ to go 64bit.
(In other words: PAE might enable you to use RAM >= 4 GB,
but your processes will still be limited to 32bit address
space.)
