This seems reasonable and we should go that route. The proposed plan (as
I understand it) would be:

 LAM removal:
 - Update mpi-defaults to use MPICH2 (in progress). binNMU all packages
   and remove LAM from the archive.

 Open MPI arch support:
 - Update openmpi to build on all arches. (Progressing, but slowly.)
 - Once we have full arch support, decide what to do with mpi-defaults.

So these are basically two orthogonal changes, and the new mpi-defaults
helps the LAM removal. I will upload a fixed mpi-defaults soon so that
the LAM removal can take place ASAP. I'm sorry for the inconvenience that
was caused by my quasi-MIA! Though times…
