I wanted to mention, along these lines, that netbsd has a command
which can program the disk controller to enter "idle" or "standby"
mode after a number of seconds.  The command is "atactl".  I looked at 
how this is done.  It's using a set of controller commands which
apparently aren't supported under FreeBSD.  The controller commands
are:

#define WDCC_IDENTIFY   0xec    /* read parameters from controller */
#define SET_FEATURES    0xef    /* set features */

#define WDCC_IDLE       0xe3    /* set idle timer & enter idle mode */
#define WDCC_IDLE_IMMED 0xe1    /* enter idle mode */
#define WDCC_SLEEP      0xe6    /* enter sleep mode */
#define WDCC_STANDBY    0xe2    /* set standby timer & enter standby mode */
#define WDCC_STANDBY_IMMED 0xe0 /* enter standby mode */
#define WDCC_CHECK_PWR  0xe5    /* check power mode */

and these are not even *defined* in the FreeBSD files.

Is there any chance of getting this supported under FreeBSD?
