Yes, in a perfect world I should just have to turn the device off in src/mainboard/thomson/ip1000/Config.lb and I would never see any traces of the device.
Quote from the 82801DB datasheet LPC register 0xF2: "Software sets this bit to disable the AC ’97 modem controller function. BIOS must not enable I/O or memory address space decode, interrupt generation, or any other functionality of functions that are to be disabled."
But just turning the device off is not performing all of the above functions required by the southbridge. If anyone has any suggestions on how to really disable this device without touching src/southbridge/intel/i82801xx/i82801xx_ac97.c I would be glad to hear them....
The code in src/southbridhe/i82801xx/i82801xx.c tries to take care of the F2 register settings. So, if you don't have a device pci 1f.6 off end in your config.lb it might just get enabled by i82801xx.c again
