It's very unlikely that you would need both it87 and w83627hf. One of
these has to be a misdetection.

Confirmed here. Do not load it87.

And quite rightly so, as it knew it was a misdetection.

Yes. Check /proc/ioports, see if something holds part of the 0x290-0x297
range. If there is something, try to recompile a kernel with
CONFIG_PNPACPI disabled. This is a known and reported problem waiting
for a solution:

The cause is IMHO a broken BIOS (or ACPI data thereof), so ideally the
motherboard manufacturers would fix their BIOS and the problem would go.
But I might be wrong.
