Имеем:

atapci1@pci0:0:5:0:     class=0x01018f card=0x08021558 chip=0x11831039 rev=0x03 hdr=0x00
    vendor     = 'Silicon Integrated Systems (SiS)'
    device     = '?SATA (?SIS966/968 )'
    class      = mass storage
    subclass   = ATA

В ядро:

device          ahci
device          ada

После чего имеем:

ahci0@pci0:0:5:0:       class=0x010601 card=0x08021558 chip=0x11851039 rev=0x03 hdr=0x00
    vendor     = 'Silicon Integrated Systems (SiS)'
    device     = 'AHCI Controller (SIS968)'
    class      = mass storage
    subclass   = SATA

И не забываем поправаить /etc/fstab, и включить в BIOS AHCI.
