My vdr-suspend patch does exactly this.  The mode variable is Setup.Suspend,
and it can be read from the configuration file.  The mode is switched by
pressing the Power button.  After a short timeout, the system will shut down,
unless it is busy with something else (such as recording or cutting).  I've
used the system since last September, and it works well in our family.

My vdr-relay plugin (for powering the screen on or off) has an option for
setting the initial suspend status.  Thus, when the system is started by
remote control (my own design for the Hauppauge Nova-T PCI 90002), the
screen will power on.  Otherwise (start by wake-on-LAN or nvram-wakeup)
the screen will remain off and playback will be suspended.
