Custom suspend script

Due to certain bugs with powersaved, I've written my own little suspend script to handle the unloading/loading of modules and daemons and the suspending itself. How do I tell ACPI to run this script when I close the lid, or trigger some other event?

Re: Custom suspend script

Create a file in /etc/acpi/events/ or edit /etc/acpi.handler.sh putting it in there.  As an example I edited the /etc/acpi.handler.sh script to this setting my custom suspend script to run when I press the power button (because it is for a desktop and that is the only ACPI button I have available)

#!/bin/sh
# Default acpi script that takes an entry for all actions

# NOTE: This is a 2.6-centric script.  If you use 2.4.x, you'll have to
#       modify it to not use /sys

minspeed=`cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_min_freq`
maxspeed=`cat /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_max_freq`
setspeed="/sys/devices/system/cpu/cpu0/cpufreq/scaling_setspeed"

set $*

case "$1" in
        button/power)
                #echo "PowerButton pressed!">/dev/tty5
                case "$2" in
                        PWRF) /usr/local/bin/suspend ;;
#                       PWRF)   logger "PowerButton pressed: $2" ;;
                        *)    logger "ACPI action undefined: $2" ;;
                esac
                ;;

I only posted the first part of the file to save space the rest was unmodified.
