I assume you're using 1.6.x-RELEASE, right?

Does this actually turn off ACPI driver?  When ACPI driver is disabled,
sysctl hw.acpi gives you nothing:
# sysctl hw.acpi
sysctl: unknown oid 'hw.acpi'

If not, choose "Boot DragonFly with ACPI disabled" from the boot menu,
or type 'unset acpi_load' on the boot loader prompt:
OK unset acpi_load
