[moved from -mobile to -stable as I think no mobile computer has an ATX M/B :-)]

It is not suppoted on -STABLE. You may want to try my patches, that implement
"shutdown -h" soft power off (attached below). This requires an APM BIOS and an
ATX M/B+PS. I'm running with this patches since 26th, and I found no problems.
To apply the patches, cd /usr/src and issue a "patch <apm-power-off.diff", than
rebuild your kernel and reboot with your new kernel. That's all.
Maybe someone should commit the patches to the -stable tree, in this ATX
days... :-)

Isn't that feature a BIOS related one? I mean: don't you have to instruct the
BIOS about the time on which the machine will be powered on?
I have a section on my BIOS that does that, but I didn't try it yet. BTW, my
M/B is an ASUS SP98AGP-X, with Award BIOS.

Yes: I grabbed the soft power off code directly from -current... :-)
