At the risk of throwing an extra spanner in the works, it's worth mentioning
that some switches have one port set aside for "uplink".  If you use this
port, the above rules are reversed, i.e. you can connect switch-switch with
an ordinary cable, or you can connect the uplink port to a client with a
x-over cable.

Some newer switches and/or all gigabit switches seem to have auto-MDI/X on
them anyway, so you can use either normal or x-over cables for connections
to anything, and the switch will work out where the pairs are.
