I look further into the problem and maybe it's not the kernels fault.
If I suspend wihtout gnome running ("suspend" from GDM) the laptop successfully
suspends more than once.

Laptop suspend works only once

I narrowed it further down: I must have 'something' to do with gnome:
- If I switch to tty1 and do "echo 'mem' > /sys/power/state" I can suspend more
than once
- If i do "echo 'mem' > /sys/power/state" from a Terminal within Gnome I can't
Also the problem vanishes if I use LXDE instead of Gnome.
