Perhaps you haven't actually tried it to see what happens. On 5.4,
there is not an extra column, but top -S includes each CPU's idle
percentage as a separate system process, so you can get some idea of
how well balanced things are.  Perhaps the description above was for
7-CURRENT and 6.1-R acts more like 5.4. I don't have a 6.1 SMP system
to test it on.

5.4 also doesn't seem to have mptables.
