Apparently the optical drive is ata_piix controlled, right?

After rebooting (optical drive plugged in):
# dmesg | grep -Ei "PIIX|AHCI"
ahci 0000:00:1f.2: version 2.3
ahci: probe of 0000:00:1f.2 failed with error -22
ata_piix 0000:00:1f.2: version 2.12
ata_piix 0000:00:1f.2: MAP [ P0 P2 IDE IDE ]
scsi0 : ata_piix
scsi1 : ata_piix

What does that mean to me now?
