Here's the patch as promised. Took the code from smsc47m1.c. It
currently only changes behaviour for the IT8712F since I cannot test
on any other IT87-chips, and the comments in sensors-detect made me
uncertain whether they really use the same key/exit sequence.
Also changed sensors-detect somewhat to support longer devids and exit
sequences. Don't know if you'll approve my perl though...

Sure, it actually was something I introduced myself :-(. I initialized the
fan_ctl register with (read_value & 0x8f | 0x77) to enable the smart
guardian feature for all 3 fans. But the power supply fan does not support
pwm. It can only be operated in on/off mode, i.e. bit 0 must be clear. I
switched it back to the original (rv & 0x8f | 0x70 ) and everything is back
to working.

Here it comes.

Copy sysctl enums to chip drivers from sensors.h for now,
as seen in drivers included in 2.5 tree. File no longer included
from kernel side.
Apply i2c-proc change in CVS tagged -km2.
Partial clean and sort of includes everywhere.
Add i2c-dev.h, as a partial copy from i2c.
Add to sensors.h from i2c-proc.h to compile things.
Remove i2c-isa.h.
Reflect header file changes to lib/ and prog/.

Module refcounting using .owner, removing of inc/dec_use.
These require (yet unreleased) i2c 2.8.0+.
Named initializers everywhere. Unified namespace.
Cleanup for 2.5, remove EXPORT_NO_SYMBOLS, declare everything
static. Apply initcalls.
PCI device registration changes for busses started, replicating
from i2c-amd*. While everything does compile, nothing really
works. Well, maybe i2c-amd* ported back from 2.5 tree.
After updating your work directory, run

BEWARE: I have not even insmoded any of these yet.
To compile, you need i2c from cvs too.
For 2.4 kernel :

For 2.5 kernel :

The following patch does the following:
Fixed bug with not all alarms enabled.
Added ability to read battery voltage
Select temperature sensor type at module load time.
Added setting for Inside Technologies 786LCD board to example config file
I also fixed what looked like a typo in the existing it87 section where
in6_min/max was set twice and in7 was not set. As commented I think
the equation for the negative voltages are wrong but without that motherboard
I can't verify.
With the 786LCD board sensors-detect reports a lm78 which doesn't
exist and a sis5595 which may be part of the SIS630 chip but doesn't
perform the monitoring. The it8705F/SIS950 which is on the board is
reported as a misdetect. I didn't know enough about the various chips
to figure out how to get correct detections.

were copied to i2c.h in the i2c package).
No harm was done because i2c-isa.h is still in our package, and
it87 is not included in mkpatch yet.
