Hmm from the bootlogs it seems that your drive does not set the proper
ATAPI signature, thats why detection fails:

atapci0: <VIA 82C686A UDMA66 controller> port 0xd800-0xd80f at device 4.1 on pci0
ata0: reset tp1 mask=03 ostat0=50 ostat1=50
ata0-master: stat=0x80 err=0x80 lsb=0x80 msb=0x80
ata0-slave:  stat=0x00 err=0x01 lsb=0x14 msb=0x80
                                         ^^^^^^^^ should be 0xeb
ata0-master: stat=0x50 err=0x01 lsb=0x00 msb=0x00
ata0: reset tp2 mask=03 stat0=50 stat1=00 devices=0x1<ATA_MASTER>
ata0: at 0x1f0 irq 14 on atapci0
ata0: [MPSAFE]

There isn't much I can do about that one except you experimenting with
the device and finding out why it fails setting the right signature....
