I have no experience with 64 bit HW, but I think it _should_ work.
The only prerequisite to make it really easy (otherwise, some more
hacking is needed, but it's still possible, I think) is having
386_64/amd64 hardware available on the install server.

Because, to install a 64bit userland system on the client, you also
need a base.tgz that contains a minimal debootstrapped 64bit system -
the 32 bit nfsroot will run on the 64 bit machine with no problems,
and it has not problem to extract the base.tgz - then, when the FAI
scripts chroot in the 64bit client system to make adjustments and
install software, the 64bit userland code runs on the client
processor.

It's possible to chose the arch when running debootstrap - so you can
create 32bit and 64bit base.tgz images on your 64bit server.
