Olivier, I may need a i386 cluster with a little old machine.
I have been observing the beowulf mailing list and I found that there are a lot
of serious conversations of energy-aware cluster.
I am kind of doing some small research on setting up OSCAR on udoo,
minnowboard, or such a toy machine and this could be pretty useful for the
energy concerning clusters. We may need to support the arm processor too.
Of course, we do not really have to support i386 and/or arm but people may be
interested in just like I am. ;-)

OK, this is done.
