I've cleaned up the patch slightly and added the fwdownload details to
the man page.  The most recent patch is here:

    http://people.freebsd.org/~emaste/atacontrol.diff

I expect this to get committed in the next couple of days, with the
intent of MFCing it to older branches which do not use ATA-CAM.  The
final goal is to get camcontrol to grow the ability to update ATA disks
as well via ATA-CAM.
