Thanks to the holiday break, I finally had some days available to render out some material for you.
First, a still of the Troll:

This is slightly higher resolution than it is in the film, so things are starting to break apart a bit. Looking at the troll at this resolution, I wish I had added particle twigs and dirt to the fur.
Here's a turntable that gives a good view of the Troll and the fur:

As you may or may not see, the fur is composed of several components. The first is the short fur (the black object, displayed as fur lines). This was done using the fur modifier, and quickly groomed into shape. A texture map controls its length. Then there's three objects with fur built using hair mesh. There's one for the non-simulated hair in the face (eyebrows, and hair in the nostrils and ears), then there's one for the hair on the body, and one for the hair on the head. The reason for doing separate objects, is because they needed separate values for the simulation. For example, the hair on the head is a lot heavier and (seemingly) sticky than the hair on the body.
Finally, here are some of the VFX shots from the Troll Hunter movie:
