Smartctl uses the ATA-Passthrough commands - the reporting there is correct. Your system on the other hand uses SCSI, that's what libata is for. You may want to also read the scsi-specs, then you'll notice that "INQUIRE_DEVICE" scsi command allows less characters for revision and model. So maybe you'll want to write a feature request to the libata devs to update the VPD via ATA commands after a disk has been detected to be ATA.
