Did you run "apm -s" as root?
What happens when you press the sleep button?
What is the output of lsmod?
In the bootup messages, is there a line about starting the apmd service?
Is there a line later on about starting the ACPI service?

Makes sense (sort of). The command fails either way, apparently because
it can't communicate with apmd.
