Recent versions of smartmontools (say 5.38 from CVS at sourceforge) don't need the '-d ata' option any more. If smartctl or smartd see /dev/sd<x> in Linux, they will assume a SCSI disk, do an INQUIRY and if they see "ATA " in the T10 vendor identification field then an ATA (most likely SATA) disk is assumed behind a SAT layer. Thereafter ATA commands will be issued, each wrapped in a SCSI ATA PASS-THROUGH(16) command. Perhaps you might check that this works with the aic94xx driver.
