It prevents sysresource subsystem from probing. The sysresource subsystem pre-allocates all memory and I/O resources on its attachment to serve as resource manager. In my limited knowledge, if the resource needed by a device is pooled by ACPI, and not its ancestors, resource allocation fails. But, as I haven't seen the bootverbose dmesg with ACPI enabled, maybe I spoke too soon (as always :). BTW there's another debugging knob, debug.rman_debug, can be set to one to get verbose information with regard to resource allocation. This increases the size of the messages to dmesg, so you may have to raise MSGBUF_SIZE in your kernel config and rebuild it. This is not a sysctl knob but a tunable, so I recommend against putting it in loader.conf (unless you have no access to the console). Cheers.
