    libata supports the acpi interfaces but has them off by default. Turn
    them on and it ought to just work assuming the BIOS does the right thing
    and the BIOS knows the password.

    FWIW, ACPI is turned on in libata-dev.git#upstream, and as soon as
    Andrew does his next update, it should be turned on there too. (it
    might even be in his last -mm update, not sure)

    CONFIG_BLK_DEV_IDEACPI=y is not enough since IDE ACPI _GTF support is disabled
    by default. To enable it "ide=acpigtf" kernel parameter should be used.

    Sometimes it may be also worth to try enabling usage of IDE ACPI methods on
    boot ("ide=acpionboot" kernel parameter) which is also disabled by default.

    We probably should switch both options to be on by default if recent libata
    transition to ACPI on by default turns out to be successful.

    PS I've updated bug #4580 accordingly.

    Thanks,
    Bart
