No. I don't think I have any pure-SATA machines. I suppose I could
disable the drivers for non-SATA and see what happens.

Its current value lies in allowing SCSI and SATA scans to take place
simultaneously; otherwise SATA forces SCSI to finish its scans before it
starts. It also allows the SATA asynchronous scan code to become
synchronous.
