University of Kentucky claims rights to almost anything (even "drawings") students make while in any of "certain University units" (including the "Computing Center"):

It's not clear whether a dorm room is one of those "certain University units" or not. I don't think so, but it'd depend on the phrasing of the dorm room mission statement.
Ooh, my new favorite is North Carolina A&T State University:
"We don't have any such policies in place at this time. The university has initiated a faculty interest group which meets regularly to discuss these issues and similiar DL opportunities. Some interesting things are coming out these discussions."
