Hello,
maybe you're interested in building an rpm of lm_sensors containing a more recent lm_sensors rpm (latest snapshot 'r4197-20061007'). Then have a look at http://lists.lm-sensors.org/pipermail/lm-sensors/2006-October/018052.html
Perhaps there's someone who wants to take over maintenance for building this rpm from the snapshots in some other repo than the base one... (I don't have time for that). At least, this rpm works for me now on a x86_64 and I thought, I'd share it with the centos folks out there. cu - Michael
