Here is an explanation of the BCS or the DI-AA that I took offline.

The NCAA Division I Football Championship is an American college football tournament played each year to determine the champion of the NCAA Division I Football Championship Subdivision (FCS). Prior to the year 2006, the game was known as the NCAA Division I-AA Football Championship. The FCS has historically the highest division in college football to hold a playoff tournament to determine its champion; its 24-team tournament is still far larger than the four-team playoff system to be used used by the Bowl Subdivision beginning in the 2014 season.

Thus, EKU and Austin Peay are DI. They are a different division of DI than Kentucky and Louisville, but, they ARE DI. The championship for DI-AA or now called FCS is won in a playoff format while DI used the BCS system until this past year. DI vs DI-AA as it was called is determined by the school and the NCAA according to how many scholarships are offered and how many scholarship sports a school offers. To be considered DI by the NCAA a school must offer 7 scholarship sports for women and 7 scholarship sports for men....or.....8 scholarship sports for women and 6 for men. That is what makes a school Division I NCAA.
So in a way, everyone is right to a degree. EKU and Austin Peay are DI, just in different divisions of DI football. That is why they are all elligible to play for the basketball championship.
