You can do what I did for Rmpi and use Open MPI where available and LAM where
not:

      Build-Depends: debhelper (>> 4.1.0), cdbs, r-base-dev (>= 2.6.0), \
	libopenmpi-dev (>= 1.2.4-5) [i386 amd64 alpha ia64 powerpc sparc], \
	lam4-dev [!i386 !amd64 !alpha !ia64 !powerpc !sparc]

Nothing wrong with that.

Are you sure that these atomic ops are the one mssing in Open MPI?  Could you
provide a proof of concept for one arch so that I could take that to upstream?
