To get the Debian kernel package version please use:
$ cat /proc/version

this is quite old and there have been important security updates since then.

You mention having this version installed:

Perhaps you had only installed/upgraded to that version after booting?

I've been using USB-attached APC UPSes from at least 2011-08 through
2012-01 and didn't experience this bug; during that time I was using
up-to-date Debian amd64-openvz kernels from stable/stable-updates/security.

I'm not sure if this test is still relevant now that sid has 3.2.x. I
haven't yet tried one of these UPSes on 3.2.x but will try to.

Indeed. The machine was up for 178 days today. I rebooted into 3.2.x a few
minutes ago, and alas: the problems are gone

Yes. Now I'm getting:
