Done.

Note that I wouldn't be surprised if most IT8702F chips were not wired
for monitoring. These chips are rare and only include fan speed
sensors, no voltage sensors nor thermal sensors as other ITE Super-I/O
chips do. Does the BIOS report any fan speed?

You may provide a dump of the hardware monitoring I/O area of your chip
and I'll tell you whether it appears to be actually monitoring fans.
This will prevent you from waiting for a driver that you don't actually
need. It's relatively easy. Take the address sensors-detect reported
the chip was at. Typically it's 0x290. Then call isadump on this
address with offsets 5 and 6, typically:

isadump 0x295 0x296

From the output I can tell you whether fans are monitored or not.

BTW, if someone wants to write this missing driver, that should be an
easy one. I would do it myself if I had the time (or if someone pays me
to do the work.)
