The down-side is that through these moves we've lost functionality each
time.  For example, the blinking heartbeat LED on the Assabet and
Netwinder which I always enabled to let me know whether the machines
were still alove has long since gone.

I hope that this series restores that functionality on those platforms
where it has been lost.
