Well, if we write a driver for this chip, it's always better to get the address from the Super-I/O configuration address space, rather than hardcoding an arbitrary address. This lets us detect much more reliably whether the device is there or not, and also lets us deal with different addresses without user intervention. -- Jean Delvare
