Actually the system would more likely heat up than cool down. The
shutdown process is rather CPU intensive AFAIK. And BIOS things aren't
optimized for CPU idling either.

VIA chipsets have an overall bad reputation (network adapters and
motherboards alike) for sure.

Unload the eeprom module, and load the ddcmon module instead. That's
what most video cards want. If your monitor supports it, the module will
return some information about it.

If sensors-detect told you to use eeprom, I'd be interested in the
sensors-detect log, and in an i2cdump of the chip at address 0x50 on
that bus.

FYI, the patches are available by now.

You should dump the chip contents and post the dump on this
mailing-list. We'll take a look and see if we can find out what it is.
Telling us what your motherboard is will help too. In order to dump the
chip contents, use: "i2cdump 0 0x2d". (Replace 0 with the bus number if
it's not 0). Make sure there's no chip driver loaded for that address,
or you may confuse that driver with unpredictable results.

Noone but me reads French on this list, methinks ;) So let's stick to
English.
