Ahh, it just took a bit more searching.  The end result is shown at [0], but 
the key elements were discovering that the class is 
Chef::RunList::RunListItem (I found good examples at [1] and [2]), but the 
key link is shown at [3]:

        but node.run_list is a Chef::RunList


The final result being shown at [0] is:

        node = Chef::Node.load('n')
        node.run_list << "role[foo]"
        node.save

Thanks, everyone!
