Putting FreeBSD to sleep?

[Graham Bentley]

Can anyone post some good pointers for setting
up ACPI or APM so that I get automatic susepend
afer x mins of inactivity and woken up on LAN
request ?
(in particular shut down disc / slow or shut
down psu fan - its the noise I am concerned
about)

I have looked at posts on rc.suspend/resume
for various power saving issues on laptops
but cant find and good resources on how to
do the above. Surely this must have been
done before by someone with a remote server
in a secret location :)

Thanks in advance for any advice :)
