Excellent - youve identified a need, and a potential author *YOU*
If you want to try, Im sure you'll get help here.
I know nothing of your chip, but perhaps someone here can scan the
outputs you provided,
review a data sheet (essential bit of info - reverse engineering w/o
specs is hard),
and recommend a best starting point for copy & edit operations.

I thought of that at first (more experienced people
claim it's basically a grandson of the lm85), but
unfortunately this particular machine is a test machine
at my company, and there's actually people working
on it. So I can't start modprobe'ing some random code
that'll crash it (it's not good behavior for an admin
to prevent users from doing their job ;-)

If it is a grandson of the lm85, I can help you. But we *need* the spec
sheet, lm85 and look-alikes are very complex chips, you have to read the
entire datasheet to not hit gotchas.

*If* the chip looks very much like an lm85 or an ATDT7463, *and* you get us
a full datasheet, we can try to do a spec-sheet-based change to lm85 and
carefully review it before you try. At least it shouldn't oops the kernel
:-) and chances are it will actually work fine.

I don't know how much like previous chip it looks, I was merely
shamelessly quoting Jean Delvare
(see <http://lists.lm-sensors.org/pipermail/lm-sensors/2005-November/014458.html>).
As for the datasheet, the job of looking has already been done for
me by the lm-sensors folk ;-) the 'new drivers' page mentions:
<http://www.analog.com/en/prod/0%2C2877%2CADT7476%2C00.html>
which includes a link to a what is described as a data sheet
(I have zero idea whether it includes the relevant datas,
but it does include 72 pages of technical stuff I understand
nothing about) :
<http://www.analog.com/UploadedFiles/Data_Sheets/402263009ADT7476_a.pdf>
Whenever there's some code to try, I can schedule some downtime
to test (I just can't do it too often).
Thanks for your help,

Romain,
I am sorry but I have had no time to work in lm85 as of lately. I didn't
forget your request, but I have done zero work on lm85 on the last three
months, which does not bode well for merging atdt7463 with the kludge fixes
I have locally for adm1027 fan support.
Just so you are not left hanging without any clue of what is going on, even
if the news are not good :(
