could it be that you need to upgrade your motherboard's BIOS firmware?
(since you mention that "auto" didn't work well)

quite likely you already have it (from your distro's stock kernel).
Try the following command:
sensors
powertop
hdparm

i forgot which one fetches the SMART related info.

Some of them are in the form of kernel modules, some are configurable
kernel configs. For example, "sensors" command needs acpi-cpufreq
module. To be precises, use "sensors-detect" command to find which
kernel modules that matches your environment.

and some of them are in the form of CONFIG_DEBUG... try to explore the
"make menuconfig". I really can't recall them on top of my head.... :)
