Being likely to be there does not them be actually there. I simply don't
want to add support "just in case" and make the driver bigger and
possibly more complex for nothing. (What's more doing this cleanly would
require me to read the data sheets for the four/five other chipsets, and
I don't have time for that at the moment.)

I added detection for the ADM1032, MAX6657 and MAX6658 in
sensors-detect. That way, if anyone has one and wants support for it, I
believe we should be told about it. I also made the message clearer so
that people understand they have to ask.

BTW, these three chips have no known die revision codes, which makes
their detection possibly unreliable. I've sent a support request on
Maxim's website but admit not to expect too much from it. I also mailed
Mary Burke at Analog Devices, maybe she'll be able to provide the
revision code values for the ADM1032.

I am now updating the new drivers page.
