Its the latest in the F10 repos, Luca. I have these:

lm_sensors-3.0.2-1.fc10.i386
lm_sensors-sensord-3.0.2-1.fc10.i386

I also note that while asus_atk0110 is loaded, it has no link count in an
lsmod output. This has little or nothing to do with the lm_sensors version,
when the kernel itself (2.6.31 final) doesn't get any real data. Or can it?

I've stumbled around is the /sys/fs tree looking for data, but wasn't able to
do anything but get stuck in a re-entrant loop, that is a bowl of spaghetti,
well stirred. You can get back out, but each suspect link just puts you one
level deeper in the tree and no real data is ever offered even when 10+
levels deep in that linkage loop.

I'll go bugzilla the F10 lm_sensors packages.
