Well, ideally, it would be possible to download a tarball that
contained the contents of
https://openfabrics.org/svn/gen2/branches/1.1/src/userspace/, minus the
mvapich subdirs, which could perhaps be a separate tgz as they are very
large on their own.

I'm willing the maintain the gentoo support for the gentoo science
overlay.  That isn't a problem.  I have already constructed gentoo-ified
versions of the OFED scripts found in '1.0/ofed/openib/scripts'.
I could potentially upload tarballs as you suggest.  For now, I'm going to
stick with subversion until my ebuilds are commited to the science
overlay, and there is potential interest in it from others.  We will have
to see.  If there are others in the gentoo community who would benefit
from it, I'd be happy to produce and upload the tarfiles as my schedule
permits, if openfabrics.org would host them.

Usually our cluster has a very up-to-date kernel.  Right now I'm being
forced to downgrade it temporarily to 2.6.12 in order to evaluate Lustre.
In the future, I plan to do as you suggest, and add SDP as an out of
kernel module.
