I have not been able to find any information on determining if the driver is indeed loaded or being utilized.
Booting a 60G USB HD ( this was an enclosure I bought for an old IDE laptop HD ), I run these commands:
modprobe -l | grep "tntfs.ko"
Couldn't figure out how to get a screen-shot into this reply but here is the output:
/#mod probe -l | grep "tntfs .ko"

description: Read/Write NTFS Driver
author: Tuxera Inc. & Anton Altaparmakov
vermagic: 184.108.40.206-0.7-default SI1P mod_unload modversions 586TSC
Does this mean it is indeed loaded?
I have performed mounts using the FS TYPE ntsf-3g which I think is Tuxera.
Hope this helps.
