    I blacklisted the k8temp driver (and the out-of-tree k8_edac driver
    in Fedora) and the temps were still volatile, so that's not causing
    it. Since then I've upgraded the system BIOS from F.06 to F.27 and
    the problems _may_ have gone away. My own custom 2.6.19 kernel has
    never been a problem, so I'm thinking it's one of these drivers
    loaded by Fedora that I never even compile:

    i2c_core
    i2c_ec
    i2c_piix4
    asus_acpi (on a Compaq???)
