Some changes happened to ACPI with the 2.6.13 kernel that comes with Slackware 10.2
You will have /proc/acpi/sleep missing. It has been 'deprecated in favour of /sys/power/state'
You will have to change the scripts described above.
New /etc/acpi/events/standby:
echo "rmmod uhci_hcd" rmmod uhci_hcd # everything before this point is sleep echo mem > /sys/power/state # everything after this point is wakeup echo "modprobe uhci_hcd" modprobe uhci_hcd
/etc/acpi/events/blank:echo standby > /sys/power/state
