Likely the only way nForce4 NCQ support could be added under Linux would be with a closed source binary driver, and no one really wants that, especially for storage / boot volume. airparrot linux MCP61 introduced a bug in the SATA NCQ implementation. ...

A value of 0 will deactivate sleep mode completely. To send the hard drive to sleep immediately, enter: hdparm -y /dev/sda. With a capital Y, the drive will go into an even deeper state of sleep. …Supports NCQ, hot sparing. Optional battery backup unit is available.

Works with a patched version of libata's sata_sil subdriver (2003-12).The industry standard interface between the software and the SATA host is the Advanced Host Controller Interface (AHCI), which allows advanced features of SATA, such as hot plug and Native Command Queuing (NCQ).
