I just did some testing just to make sure that my system resets on the 
same line. Sadly that is the problem, writing PM1A resets the machine.

I also compared the code with hwsleep.c from linux 2.6.10. They almost 
exactly the same, except for at one point but that should only affect 
S5. Everything else is the same.

I have no idea of where the problem is but I'm willing to debug the code 
if someone tells me where to look. Should I maybe address the issue on 
freebsd-current as the problem might be in the device drivers?
