Should be supported by i2c-sis96x, yes.

Right, that's on my to-do list for some times already, but couldn't find
the time to fix that problem yet, sorry.

It shouldn't. And you shouldn't try to load it, as it might confuse your
bus.

Not really, except ths sis5595-might-have-confused-your-bus mentioned
right above.

Make sure you have sysfs support enabled in your kernel and mounted
under /sys on your system. Check your dmesg for possible hints, and
have a loot at what /sys/bus/i2c contains.

You could also unload it87 and run i2cdetect on your sis735 bus, to make
sure you see your it87 chip there (I expect you to see it if
sensors-detect suggested it). If you can see the chip, run i2cdump on
it and we'll try to understand why the it87 drivers did not like it.
