These drivers don't really get included in GENERIC kernels (at least, 
not on amd64/i386) since the i2c bus isn't really probe-able, and the 
devices all share a common i2c address (0x2e).  This really wouldn't 
affect GENERIC kernels at all.

Now, I'm not at all sure about OpenFirmware ports, where there's an 
external source of configuration information that doesn't require 
probing of the i2c bus.  I don't know if any of these devices are 
included in those GENERIC kernels.  Michael, any guidance here?

So far, I've identified ten different chips that all could be easily 
handled by a single driver, with trivial detection of the specific chip 
based on two on-board registers.

        adt 7460, 7463, 7466, 7467, 7468, 7473, 7475, 7476, & 7490
        adm 1027

All of these are identified externally as "dBCool (tm) thermal monitor 
and controller" and all made by ON Semiconductor (they bought the 
product line from Analog Devices at the end of 2007).
