I tried pressing the power button for a longer time.  It does actually do 
something.  After about 4 seconds, it has the same effect as "shutdown -p now" 
or "halt -p", that is, the video card stops working, the fans keep going, and 
the disk access light comes fully on.

I am guessing that this 4 second delay is part of how FreeBSD wants it.  If that 
is the case, it shows that the power button is working as it should - it is the 
power-down process that is not working right.
