I'll do my best.

Looks OK. Any additional patch (ACL, GRSEC) applied?

That's perfectly normal, see below.

Either because "sensors -s" failed, or because these voltages aren't
used on your system (most systems don't use these voltages anymore, so
some don't bother monitoring them).

This is normal. These files only advertise about existing busses. Real
files are in /proc/sys/dev/sensors.

Move to /proc/sys/dev/sensors, and show us what "ls -lR" returns.

We have had half a dozen reports of problems similar to yours, and I
have to say we never really found what was causing the problem (so
couldn't solve it). If you system is specific in any way, please let us
know (of course, i's hard to say what "specific" means here, since we
don't really know what we're after).

It's not mine either, but we understand each other, isn't it? :)
