Public bug reported:

Binary package hint: linux-image

Neither /proc/acpi/alarm or /sys/class/rtc/rtc0/wakealarm exist on the
Hardy Heron kernel 2.6.24, so no mechanism exist for waking up a
sleeping/powered down computer. Gutsy had /proc/acpi/alarm, but
apparently that mechanism has been deprecated since 2.6.22.

Here's more information on the subject matter:

# uname -a
