If my information is correct, there have been 11 split national championships as awarded by the AP and UPI (now BCS) since 1954, although most probably only remember back to 1978. Starting that year, it was (AP Champ/UPI-BCS Champ):
1978 Alabama/USC 1990 Colorado/Georgia Tech 1991 Miami/Washington 1997 Michigan/Nebraska 2003 USC/LSU
The Washington Huskies and Miami Hurricans split a title in the 1991 season.
I have a sweatshirt that claims 10 National Championships. 2004 marks the 11th.
Nebraska and Michigan split a title in 1997 also.
