patch moves SMC device into SSDT and creates it only when device is present, which makes ACPI tables smaller in default case when device is not present. Also it fixes wrong IO range in CRS if "iobase" property is set to a non default value. PS: Testing with XP shows that current default "iobase" used SMC device conflicts with floppy controller IO, but it's topic for another patch and I'd leave it to SMC device author for resolving conflict.
