Thanks a lot for answering!

Yes, I realize that. Unfortunately it seems that S1 is my only option  
to somehow turn the laptop silent and still be able to wake it up by  
external (USB) device

Nice idea! I tried that and it didn't help:-(. There's another hint  
that suggests that not only video doesn't fully recover: the pcmcia  
network card doesn't come up again. I can't ping the machine and the  
activity leds on the card are out as well after a wake up by USB.

hibernate is a ubuntu package that offers quite a lot of tools and  
configuration options for suspending the machine. But since the hard  
way (writting standby to he /proc/acpi file) results in exactly the  
same way I think it doesn't matter if I use the pm tools (tried that  
as well btw:-))

I realized one more thing: the last screen before going to sleep looks  
exactly the same as the one after wake up by USB: blinking cursor on  
the forth line on a otherwise black screen

I tried various boot options, but maybe someone can point out some  
that might help?
