You can find tables of 2011 winter test data for the HakkaR and the Xi2 at these two links (One Norwegian, one Russian). Google Translate will be your friend.

Just as an example, for braking on snow from 80 km/hr, the Xi2 required 54.9m, and the HakkaR required 54.7m. For accelerating on snow, it was 5.2 sec vs 5.1 sec.
For braking on ice from 50 km/hr, the Xi2 required 56.3m, and the HakkaR required 61.8m. For accelerating on ice, it was 7.4 sec vs 8.6 sec.
There are also ice and snow handling tests, and ice and snow subjective ratings at these 2 web sites.
I haven't examined all the data in detail, but so far my impression is that the Xi2 is significantly stronger on ice than the HakkaR, but is slightly weaker on snow and slightly weaker on wet braking.
Auto Review has a nice summary table at the bottom of the page, so you can easily compare strengths and weaknesses of each tire.
