Yes.

  % otp_src_R9C-0/bin/erl
  Erlang (BEAM) emulator version 5.3 [64-bit] [source]

  Eshell V5.3  (abort with ^G)

To make 100% sure I did

  % file otp_src_R9C-0/bin/amd64-unknown-freebsd5.1/beam
  otp_src_R9C-0/bin/amd64-unknown-freebsd5.1/beam: ELF 64-bit LSB executable,
  AMD x86-64, version 1 (FreeBSD), for FreeBSD 0.0.1, dynamically linked
  (uses shared libs), not stripped 

The FreeBSD support for opteron is experimental and the gcc 3.2.2 used
is not very stable (had to go down to -O1 to compile "erl_vector.c")
and probably not very optimized for opteron yet. I tried running a 32
bit Erlang to compare the 32 and 64 bit results but it segfaults.
I'm sure there are more mature Linux ports to opteron and I think
there will even be a Microsoft Windows version soon.

If I exclude the port IO test and bypassed the test server I could
run estone. In 32 bits on the same machine I get

  **** ESTONES = 69695 ****  (not a true estone result, port io test is missing)
