Well, forget everything I said about the BIOS and new device ids: I was 

Running "lspci -nnvv" gives the following:

00:1b.0 Audio device [0403]: Intel Corporation 82801G (ICH7 Family) High 
Definition Audio Controller [8086:27d8] (rev 02)

I mistakenly thought "lspci -nn" was the correct command.  This gave the 
vendor info, not the device into.  Sorry for the noise.  I feel like a tool.

But, I'd still like to help debug the headphone jack sensing and module 
option if possible.
