I have a feeling that Michigan cares even less than Berkeley (for example, Michigan does not have an equivalent of Berkeley's "Mathematical Opportunity Committee").
Fun fact about Michigan: not all admitted applicants are offered the same amount of funding. The graduate director can and does distribute departmental funding for grad students any way he like; some admitted students will be offered $30K for a TA position and others only $16K. Another fun fact: he will make calls to find out how interested you actually are in Michigan. If Michigan is high up your list, make sure that your professors know that.
