Just been chaseing up some post install loose ends, one of which was
getting the 'automatic power off on halt' to work...

The steps required turned out to be:
a. apt-get install apm
b. echo apm >>/etc/modules
c. echo 'options apm power_off=1' >/etc/modprobe.d/apm

which seems to have done the trick nicely.

However I am a little concerned about the messages produced when apm
is loaded:
        apm: BIOS version 1.2 Flags 0x03 (Driver version 1.16ac)
        apm: disabled - APM is not SMP safe (power off active).

This is a SMP motherboard with two cpu's installed:
        Intel MultiProcessor Specification v1.1
            Virtual Wire compatibility mode.
        OEM ID: INTEL    Product ID: 440GX        APIC at: 0xFEE00000
        Processor #0 6:8 APIC version 17
        Processor #1 6:8 APIC version 17
        I/O APIC #2 Version 17 at 0xFEC00000.
        Enabling APIC mode:  Flat.  Using 1 I/O APICs
        Processors: 2
        
So is the message about apm being disabled lying - it is doing something
as it is enabling my auto power off, and /proc/apm appears showing:
        penemunde:/etc# cat /proc/apm
        1.16ac 1.2 0x03 0xff 0xff 0xff -1% -1 ?

I have skimmed through the apm source, at it looks to me like it is just
that the message is a listtle misleading and that the power off part
of apm is safe with SMP, and the unsafe bits are disabled.

I think this is right, but thought it worth mentioning as it seems like
something that should be in an Etch FAQ..
