37s is ridiculous. i'm on an eee pc with crap-for-all everything, and it
takes < 5s. presumably, it's ubuntu as the slow-poke. here's my hib.sh
script, mmv:

#!/bin/sh
. /home/peterjh/.bash_functions

if [ $USER != "root" ]; then
        echo "User must be root."
        exit 0;
fi

logger -t hib "Start";

chvt 12

#snd_mute

sync

#logger -t hib "Umt";
/home/peterjh/bin/safe-umount.sh

wifi_file=/tmp/.hib.nyu.tmp.$$
if [[ `wlan_get_ap` == "nyu" ]]; then
        logger -t hib "Stopping network because AP is $AP"
        wlan_kill
        touch $wifi_file
else
        logger -t hib "Not stopping network because AP is not nyu but $AP"
fi

# discover video card's ID
#ID=`lspci | grep VGA | awk '{ print $1 }' | sed -e 's_AT_0000:@@' -e 's@:@/@'`
# securely create a temporary file
#TMP_FILE=`mktemp /var/tmp/video_state.XXXXXX`
#trap 'rm -f $TMP_FILE' 0 1 15
# dump current data from the video card to the temporary file
#cat /proc/bus/pci/$ID > $TMP_FILE

logger -t hib "Suspending";
echo -n mem > /sys/power/state
logger -t hib "Resuming"

# restore video card data from the temporary file on resume
#sudo -- cat $TMP_FILE > /proc/bus/pci/$ID
# remove temporary file
#rm -f $TMP_FILE

#snd_unmute

if [[ -f $wifi_file ]]; then
        rm -f $wifi_file
        logger -t hib "Not bringing ny network back up to be safe..."
        # wlan_unkill
fi

if [[ `pgrep X` != "" ]]; then
        logger -t hib "In X. chvt 7"
        chvt 7
else
        logger -t hib "Not in X. chvt 2."
        chvt 2
