Nills,
Here is what my make shift solution has been.  I use gdm to login, and 
I'm on gentoo so adjust as needed for your self.  I just remember that 
to kill what I'm running before doing this so as to prevent a loss of 
data and such.
I put this in my default.sh under the heading of 00001004) which is for 
the S3 sleep when hitting fn-f4.

                                                rmmod ehci_hcd ohci_hcd 
uhci_hcd
                                                gdm-stop
                                                /etc/init.d/xdm zap
                                                rmmod fglrx
                                                echo 3 > /proc/acpi/sleep
                                                modprobe fglrx
                                                modprobe ehci_hcd
                                                modprobe ohci_hcd
                                                modprobe uhci_hcd
                                                /etc/init.d/xdm start&
                                                ;;

So far I havent had any issues with this yet, but I have noticed that 
sometimes leaving my laptop idle for a length of time allows it to just 
turn itself off, I had a similar behavior with APM, but instead it would 
sleep.  Do you know if there is some sort of way to prevent this - as 
its pretty annoying when it happens and your on AC or such.  I have 
looked through the BIOS but didnt see any ways there to prevent it neither.
