Subjecthdparm -M acoustic management for sata disks?

Dear all,

why is acoustic management via hdparm not supported for sata disks?

# hdparm -M /dev/sda

/dev/sda:
 acoustic      = not supported

# sudo hdparm -M 254 /dev/sda

/dev/sda:
 setting acoustic management to 254
 HDIO_DRIVE_CMD:ACOUSTIC failed: Input/output error
 acoustic      = not supported

Is there any patch flying around that already enables this or even any
ETA in the current mainstream?

Thanks!
Soeren
