You power down? With the button? I reboot with resume=/dev/hda13 in

boot cmdline and linux complains about not being shutdown right,

cycles through all the steps anyway.
swsusp only works if you have one and only one swap partition mounted.
i always boot with resume=<my swap partition>, and the "echo 4" causes a
switch to another tty, and i can watch the progress dots as it swaps out
memory and then writes the remaining memory image to the rest of the
swap partition. when it finishes, it powers down my notebook for me
through an acpi call, i guess.
next time i boot (with the resume=<swap partition>), the resume code
recognizes the signature at the front of the swap partition and resumes
from that.
i'm not sure if specifying the resume= kernel option is key for normal
boots from which you'll suspend.
