FreeBSD AMD64 or i386 will run on an Opteron.  IA64 will definatly not.

Yes.  This will be a good choice in many cases because third-party app
support is still better.  Hopefully this will change by 5.3 or so.

In i386 4GB unless there is PAE support (I'm not sure).  With amd64,
more then existing motherboards support.

Both of the opensource MPI implementations work fine and have ports
(MPICH and LAM-MPI.)  I don't know of a free OpenMP implemenation with
FreeBSD support, but I haven't looked either.

Neither.  This is a FreeBSD list. :-)
