    I don't know if anybody still uses one of these subnotebooks. I still have my dv2 and I have been tweaking it lately. I installed a Seagate Momentus XT hybrid HDD and was hoping to find a way to enable AHCI to benefit from NCQ.

    The key is AMD's RAID/AHCI drivers for Windows, or to use Linux because the driver there works too. These drivers bypass the system BIOS and put SB600's SATA controller into AHCI mode.

    AMD doesn't make it apparent, but there is a SB600 driver available within the Catalyst 12.6 (and possibly newer) RAID driver packages for XP and Vista/7. This driver can be slipstreamed for XP (e.g. with nlite), or installed by USB flash stick with Win7 setup.
