ahci: attachment to atapi device

Hi,

I just tested the new ahci driver on a Core 2 machine with ICH7 chipset.
It attachs to a SATA DVD burner, which I believe should be left to the nata
driver.
Kernel is 2.3.1 GENERIC with SMP enabled (no apic).

Details of chipset (pciconf -lv):

atapci0@pci0:31:1:      class=0x01018a card=0x58428086 chip=0x27df8086 rev=0x01 hdr=0x00
vendor   = 'Intel Corporation'
device   = '82801G (ICH7 Family) Ultra ATA Storage Controller'
class    = mass storage
subclass = ATA
atapci1@pci0:31:2:      class=0x010601 card=0x58428086 chip=0x27c18086 rev=0x01 hdr=0x00
vendor   = 'Intel Corporation'
device   = '82801GB I/O Controller Hub SATA cc=AHCI'
class    = mass storage
subclass = SATA

Parts of dmesg:
