Looks like the latest Super-I/O from ITE, the IT8726F, which we do not
support yet. At first sight it appears to be very similar to the
IT8716F, which we do support since 2.6.18, so it should be possible to
add support to the it87 driver easily. There are some technical details
which are unclear in the datasheet though, so I'm waiting a bit before
going on.

Do you have the possibility to recompile your kernel and lm_sensors
with some patches applied?
