Cirtainly these boxes are getting near end-of-life.  I am not sure how
many are out there beyond our the ones we have in the lab.  We do
maintain regular testing on them, even reporting them to TKO.

The main reason we bother keeping them working is that they have a large
numa ratio and tend to show up issues with other things, like the numa
scheduler issues when we got that latest re-write.

I has always been a shame that support wasn't included in generic, and
as a result we have ended up with this three way split "generic, voyager,
and numaq".  It made sense at the time for developers, but never did for
those down the food chain; particularly for distros.
