 The second stage will be to make the powering off of devices more automated.
 This is still in early design stage.  It may involve a powerd, it may
 involve intelligence in the kernel.
+
+Other stuff:
+
+- Make the DPMS support in acpi_video a separate driver that attaches to
+  vgapci0
+- Automated idle device power management
+  - Basic idea is that when a device is idle for a specified amount of time,
+    it should power down into D1 or D2.  For example, NICs can power down
+    when they have no link until they get link.  Audio controllers can power
+    down when they aren't open, etc.
+  - Want to avoid having lots of scaffolding in device drivers.  So we need
+    to come up with some models for some frameworks.
