``Too fast fans'' problem with it(4)

[Alexander Yurchenko <grange_(_at_)_rt_(_dot_)_mipt_(_dot_)_ru>]

There were many reports about fans starting to spin very fast just after

it0 at isa0

Here's a fix that prevents it(4) driver from resetting bios settings. If you
have such hardware and noticed this problem please test and report if it
helped.
