hi since my last comment I tried some changes in /etc/default/acpi-support
and now I'm able to coming back from S3. I tried it twice 1 going to sleep and
moving to an other place
in this case suspend for more than 30 min and second shortly wakeup again after
suspend.
The packages are shown in the last comment.
