Also, for what it's worth, the buildbot config can be changed to some
constant other than '5' for the recent builds list, but it would still
be only a constant across all builders. From the buildbot docs:

/builders/$BUILDERNAME
  This describes the given Builder and provides buttons to force a
build. A numbuilds=argument will control how many build lines are
displayed (5 by default).
