What does that revision number correspond to in FreeBSD release numbers? (e.g. 9.3, 10.0)

For that USB ID (09AE/3016), usbhid-ups is the correct driver.

In a message on nut-upsdev, Marco Walther just cited this thread: http://thread.gmane.org/gmane.comp.monitoring.nut.devel/6482 which mentions that the UPS works on Debian Linux 7.1. Marco's patch is against NUT 2.7.3, and it just corrects some scaling of the variables, so it would have gotten well past the problem you mentioned. It sounds like this might be an issue with the FreeBSD USB stack.

I am not familiar with NAS4Free, but what do you get when you start the driver in debug mode? You will need to get to a root shell, then run something like "/usr/local/libexec/nut/usbhid-ups -a upsname -DDD" (replacing "upsname" with the name in ups.conf). Apologies in advance if you need to go hunting for the exact path of the driver or ups.conf: the last person to have an issue with NAS4Free did not get back to the NUT lists with the ./configure settings that NAS4Free uses to compile NUT.
