    Don't leave Value32 uinitialized (as it's not completely filled)
    
    OsdHardware.c:AcpiOsReadPort() casts Value to (u_int8_t *) resp.
    (u_int16_t *) when assigning, thus leaving the upper region of Value32
    untouched. If Value32 isn't initialized, random data remains trashing
    the whole value.
    
    Without this every bus_space_read_[12] is virtually screwed up.
