I believe so, as my Load Cycle Count still increments fairly quickly
when let.  Though as long as you have "options ATA_CAM"
(it appears to be in GENERIC, so you should, I suppose) you
can also use variations on:
/sbin/camcontrol cmd ada0 -a "EF 85 00 00 00 00 00 00 00 00 00 00"
to shut off naps & such as well.
