I'm not sure about this, but think acpi suspend is something which the
kernel manages rather than Myth. You have to have special modules or
stuff compiled into the kernel, I believe, which allows it to detect
inactivity and go into suspend mode. It seems to be hard to set up
because if you have sylogging activity going on all the time, for
example, then it will never think it's idle and it won't work. Also,
it's quite new and not that mature.
Mythwelcome uses nvram wakeup which is a user space application. The
combination of these:
a) writes a date/time to the BIOS for when the PC should restart
b) runs some checks to ensure it's OK to power down
c) executes the power down command
So Mythwelcome and 2 acpi suspend are 2 _different_ solutions to
achieve a similar goal.
Happy to be corrected on any of this.
