No ... ATA_12 is opcode 0xa1 which is BLANK to MMC devices, hence we
should only use it for non-mmc devices. However, the point I was making
is that actually only disk devices should use ATA. ATAPI is really SCSI
encapsulation over ATA, so it doesn't really make sense to send ATA over
SCSI encapsulation to ATAPI devices, we should just send plain SCSI
(crosses fingers and hopes MMC devices never do smart).
