Load_Cycle_Count and ATA APM

I noted that when idle, my laptop HDD increases the Load_Cycle_Count
(193) approx. each ten seconds, as reported by smartctl. Have recently
read about the Ubuntu and APM mode for hard drives, I searched for the
tool to tune APM (that has functionality similar to linux' hdparm -B).
It seems that FreeBSD does not have a tool ? Am I wrong ? In case I did
not make a mistake, below is the patch that allows to manage APM state
of the hard drive using atacontrol.
Any comments or objections against committing this ?
