The problem itself is described correctly but it doesn't only occur after 
crashes, I also can't use powerd after normal startups. I can't determine 
a pattern when the problem occurs, it seems to occur after the notebook 
was powered down for some hours... Like I wrote in the original mail, only 
starting XP solves this.

Additionally acpiconf -s3 doesn't work.
The system goes down and I see the suspend-LED blinking but after switching 
on it doesn't wake up. The LCD backlight stays off and also the harddrive 
doesn't start. Only the usual power LED is on.

I'd love to have FreeBSD on my notebook, at the moment I could do tests if 
somebody has an ide what could be wrong.
