I'm not sure I understand why you differenciate "W83L785TS_S" and
"W83L785TS_S diode". There's a single temperature measured by the
W83L785TS_S anyway, or did I miss something?

OK, so I defintely missed something. To me, the thermal diode vs.
thermistor is something the BIOS should set, matching the way the
hardware manufacturer designed and wired the board. That's something I
would better leave untouched.

We could see the same things on some dumps contributed by one user. See
there for the whole thread:
http://www.nforcershq.com/forum/viewtopic.php?t=23918&sid=8e6f3b6d097334d2c105967163817e83
The important thing is that occasionally, reading from the chip would
fail for that user (resulting in XX on the dump, instead of the value).
Another user seems never to suffer from that (but a couple of shots may
not be enough to conclude).

I don't have a datasheet for the W83L785TR. I could find one for the
W83L785R, and fortunately it has a different ID (50h instead of 70h).

OK, I think I'll write a very simple driver (simply reporting the value
of register 27h, no more). I won't even add support to our library and
tools, just the driver.

BTW you didn't really answer my question. Do you use the registers 53h
and 85h in any way?

Thanks.
