I do know that IBM laptops have to have network interfaces ifconfig'ed 
down to suspend.  Here's my /etc/apm/suspend:

#!/bin/sh

logger -p local0.info -t apm "suspending"

sync; sync; sync
for i in $(ifconfig -l)
do
        if [ -f /etc/ifconfig.$i ]
        then
                ifconfig $i down
        fi
done
sync; sync; sync

sleep 3
