Thanks, even though I haven't tested it yet.

I just use a plain 2.6 kernel w/o additional patches, so my S4 mode  
is done using "swsusp". No unusual kernel parameters.

I posted my scripts a while ago on the VDR-Portal - sorry the  
comments are in german:

Some parts of the script are responsible for a automatic reboot after  
a timer change to set the alarm clock using NVRAM. After the reboot  
the script sends the machine to sleep.
