AMD64 vs i386 for FreeBSD

Well I just got an email back from the manufacturer of the AMD64 laptop I
wanted to buy. Im not sure how it works when switching 64 to i386, but they
say it's not supported in the BIOS(I assume this is where it is suppose to
be changed) So now I come to a cross roads:
1. Buy a 1.7 Centrino
2. Buy a P4 2.8GHz w/ HT
3. Buy the AMD64 laptop

What is the state of the AMD64 version of BSD? Other than that im leaning
toward the 1.7GHz Centrino, but I hear a lot of problems with FreeBSD
working right with Centrino, is this correct? What are the issues?

Yes, current AMD64 CPUs are fairly lower power even without the
low-power models.  We're seeing 1U dual Opteron boxes running at less
then 100F under load.
