Non wanted auto resume after suspend to ram (linux)

Suspend to ram can be a bit tricky. I've not been able to use it for some time because 2 seconds after the hibernation, my PC was resuming. Wake on network is disabled in the BIOS but I've been able to solve this problem by deactivating the driver of my network card before hibernation.

/etc/hibernate/blacklisted-modules :
r8169

To find the at fault module I've dichotomized all of them :

rmmod 10 modules
hibernate-ram
...

update 17/07/10

If fact the PC was awaken by WOL. Any packet can awake the PC, not just WOL packets. To solve this I used :
/usr/sbin/ethtool -s eth0 wol d
