As per the specifications from the vendor:
- "M1543 Preliminary Data Sheet", "M1543: Desktop South Bridge",
Acer Laboratories Inc., January 1998, Version 1.25, p. 78
- "M1543C Preliminary Datasheet", "M1543C Desktop Southbridge",
Acer Laboratories Inc., September 1998, Version 1.10, p. 126
Both the ACPI I/O and SMB I/O registers should be mapped into I/O space,
but the second quirk used to claimed an I/O resource from the memory
window which is not correct.
