Hmm, from XF86Config(5):


       Options
              Some Option flags that may be useful to include in 
Monitor  sec-
              tions (when needed) include "DPMS", and "SyncOnGreen".


Now, I have:

    Option   "DPMS"

          in /etc/X11/XF86Config, and my monitor does what I call "sleeping"
after a period of inactivity, but I can't say how this really coincides with
the current discussion, as I'm jumping in mid-stream and can't even seem
to find Lowell's reply to you anywhere (other than what you quoted).

Hmm, what about acpi(4) ?

HTH,
