I don't know anything specific to Madison, but things that are always useful in the dorms:
2-ply cushy toilet paper (the provided stuff sucks!)
A hot-pot (very useful for Mac and Cheese)
A pizza maker (shh.... I don't know if they are allowed in the dorms there)
Hot chocolate (always a good thing)
Her favorite flavor of gatorade and dramamine (good for those hung over mornings)
Picture frames or a tack board for messages, memos, memories etc. (whoooo... that's a lot of M's)
I might think of more stuff.
