Are you sure 8.0 will support NCQ? I've searched for "NCQ" on the  
freebsd web site (using google), and found nothing about it's  
implementation in the system.
Wikipedia states that "FreeBSD fully supports AHCI and NCQ since  
version 8.0" <http://en.wikipedia.org/wiki/Native_Command_Queuing> but  
gives no reference.
