Ok, so searching into Hillcrest Laboratores' patent holdings... *most* of the possibly-applicable patents are very new.
This one i feel is the most likely, and as they filed it in December of '06 Nintendo has about a month's head start on them for the purposes of prior art, not even counting the fact that they probably have patents of their own that were filed before release.
This one is also likely, and was filed May, 2007. I think they're even more SOL on that one through prior art.
They might be hoping on this one or this one , but the first is seemingly irrelevant, and from what we know of the Wii remote it doesn't follow the behavior indicated by the second, which would lead me to believe that it wouldn't infringe.
All their other patents are design patents, which I can make no claim on because for some reason I can't see the images on the USPTO's website.
Please, PLEASE do NOT feed the trolls.
