That last sentence: I infer that a switch will accommodate the lowest
common speed so that plugging any 10 meg device into it will cause it
to throttle down to 10 meg on all lines.  Is that right?

The router itself is (apparently) limited to 10 meg.  So if I plug
the router into the switch, that defeats the purpose of your
suggestion, doesn't it?  What am I missing?

According to that logic, the diagram below shows your suggested setup
but the speeds indicated aren't possible because the switch won't
accommodate the mixed speeds.
