Look at /etc/powerd/scripts/* -- they're supposed to handle all of
that.  Briefly, they do some housekeeping, then do the magic sysctl

Btw -- the default script for 'close lid' doesn't suspend, as I recall,
but it's easy to change.

Platform-dependent, but that's generally it.  On my Thinkpad, hitting
the Fn key will work, too.
