[LinuxBIOS] Read SPD issue

[Feng, Libo]

Generally, I2C mux has some external pins to set its address. In my Tyan S3992, the address is 0x71, so the function activate_spd_rom is called before accessing SPD.

Not sure, what is the typical address for a i2c mux? I can probe for it. The only other device i think there is, is the on-board tv-out chip, and I think that is at 0x88. How come lm-sensors default is to only probe between address range 0x03-0x77?

Thanks - Joe
