Jim Tressle won 3 national titles with Division I-B (now called FCS) Youngstown State before taking over at Division I-A (FBS) Ohio State and winning one there as well. However, I'm not aware of any coach winning national championships at two different Division I-A schools, which is most likely what you're asking about.
Nick Saban, however, stands a pretty decent chance of accomplishing the feat this year. If his Alabama team can get past Florida in the SEC Championship game, the Tide will roll over Texas in the National Championship Game. Saban already has one national championship with Louisiana State University in 2003.
Bear Bryant's 1950 Kentucky squad went 11-1 and defeated the #1 Oklahoma Sooners in the Sugar Bowl. However, Bud Wilkinson's Sooners were named National Champions by the AP and the UPI because both selected their National Champion before the Bowl Game. The Wildcats were #1 according to the Sagarin rankings. However, the AP and UPI were major selectors and Bryant's Kentucky squad was not considered National Champions.
No. Jim Tressel has come the closest, winning the national title in Div. II with Youngstown St. in 1999 and then with Ohio St in 2002 in Div I-A.
