It's interesting to know that current acpi-support in Debian unstable (1.109-5) has this comment in /etc/default/acpi-support:
# Note: to enable "laptop mode" (to spin down your hard drive for longer
# periods of time), install the laptop-mode-tools package and configure
# it in /etc/laptop-mode/laptop-mode.conf.
#
# (Note to upgraders: earlier versions of the acpi-support package contained
# an option to enable/disable laptop mode. This option has never actually
# worked, and for that reason it has been removed.)
