Hmm, setting debug.acpi.disabled in this way is a bit hacky.  It might
be fine however if there's no way for the user to set it before booting
the kernel (as opposed to haing the relevant drivers explicitly disable
themselves under Xen which I think would be cleaner, but would also
make your patch larger)
