OK, it works, but there's a problem : the xfce-mixer.

With many sound cards all applications using the sound device must be 
closed before suspending, else the driver is broken on resume.

My xfce hibernate script does something like  :

/usr/bin/xfce4-panel --exit
 ** call suspend script **
/usr/bin/xfce4-panel &

It usually work very well out of the session logout dialog, but not in 
the current case.
