====================================
In a really perfect world:
echo 1 > /proc/acpi/sleep # for standby
echo 2 > /proc/acpi/sleep # for suspend to ram
echo 3 > /proc/acpi/sleep # for suspend to ram, but with more power conservative
echo 4 > /proc/acpi/sleep # for suspend to disk
echo 5 > /proc/acpi/sleep # for shutdown unfriendly the system
and perhaps
echo 4b > /proc/acpi/sleep # for suspend to disk via s4bios
