The viapm module build had what appear to be some debugging CFLAGS left
around to force the IO port to a fixed address. They were only turned
on in the module build and were present since the origin

The viapm module build had what appear to be some debugging CFLAGS left
around to force the IO port to a fixed address. They were only turned
on in the module build and were present since the original import. This
breaks soft power-off on the Asus A7V since it reprograms the SMBus base
address to a different one than the BIOS expects. A similar issue was
found in the alpm(4) module build.
