It is related to the sysresource acpi memory objects. It means that something was using the system resource before acpi allocated it. For #1, that looks like lowmem up to the VGA range. For #2, it looks like option ROMs. The BIOS has configured the devices beforehand so as long as everything works, the msgs can be ignored. -- Nate
