I'm not so familiar with the cyberpower driver. But I looked in the svn
and it seems that the powerpanel driver is on it's way to replace it.

Think Arjen is the one that know all about this.

If you can try out the powerpanel driver and report back what it say
and if you get the same data stale.

Or, is it possible that new setup inject noice into the communication cable?
I hade this on one ups, where I got a ground-loop with the cable.
