  The "LEDs on the spine of the board" design goes back to the earlier
rackmount chassis, in which one could walk behind the racks and see
the LEDs.

  The NetBSD LED support isn't for those LEDs, if memory serves...I
believe it's only for the front panel LED on the SPARCstations, which
is also controlled by software.
