  Well, it has probably been done, because windows is able to do it (on the
same computer) ! As for Linux, apm's doc talks about it, but it is not clear at
all.

  Is it a desktop ? That seems very nice indeed...

  Yes. I compiled APM with "Enabled at boot time" and "Power off on shutdown".
The package you're talking about must be apmd. It seems to be what I need, but
I don't understand anything to the doc, and the /etc/apm directory is almost
empty :-( Maybe apmd is limited to laptops... I really don't know.
