With ACPI enabled in the BIOS...
        With CONFIG_ACPI disabled, USB ends up on IRQ 19 and works.

        With CONFIG_ACPI enabled, USB doesn't try to share IRQ 9 with ACPI -
        it ends up on IRQ 10, but doesn't ever receive any interrupts.
        Kernel says on bootup: ACPI: "ABIT" found at 0x000f7550

        acpid says S5 not supported, as I said before.

With ACPI disabled in the BIOS:
        With CONFIG_ACPI disabled, USB ends up on IRQ19 and works.

        With CONFIG_ACPI enabled, USB is on IRQ10 and doesn't get IRQs
        Kernel says on bootup: ACPI: found PIIX4 at 0x4000

        acpid: started
        acpid: FACP @ 0x012d3400
        acpid: DSDT @ 0x00000000
        acpid: cannot map FACP

Note that the CONFIG_ACPI kernel was 2.3.42 and !CONFIG_ACPI was 2.3.46 - in
case that makes a difference.
