Here's a little blurb I found on the Sports Illustrated web site:

"It might not have the history Boston's Beanpot tournament, but The DQ 
Cup is about to take collegiate hockey in Minnesota by storm. The 
tournament lasts throughout the season and pits Minnesota State, St. 
Cloud State, Minnesota Duluth and Minnesota in a dozen head-to-head 
games to determine a winner. No offense to Boston, but we'd take a DQ 
Blizzard over a pot of beans any day of the week."

I then found a mention of it on the University of Minnesota web site:

The cup will be based on regularly scheduled games throughout the 
season.  It is not all the games that each team plays against each other.
