Had the same problem where powerd would hang my HP Pavilion dv8000
system.  I worked arround the problem by using the following in
rc.conf:

powerd_enable="YES"
powerd_flags="-a maximum -b maximum"

Of course this makes powered do nothing when on battery.  What I think
is happening is that powered is too aggressive in downgrading the
clock speed, that it eventually sets the clock to a value that is so
low that the system stops responding.
