At some point in time, the i2c-i801 driver caused problems on a few
systems. They decided that blacklisting the driver for everybody was
the easiest way to fix the problem. Of course this doesn't make any
sense and should be reverted. The root cause of the problem should have
been investigated back then. Maybe it's fixed by now and they will
never now...
