This is what wikipedia says about reviewable plays in college:
"In 2006, the NCAA Football Rules Committee enacted instant replay guidelines and added them to the football playing rules. For games involving two schools from the same conference, league policy determines whether replay will be used. For non-conference games, the home team makes the determination.
Plays involving the sideline, goal line, end zone and end line, as well as other detectable situations, are reviewable (e.g., fumble/no fumble, pass complete/incomplete, touchdown/no touchdown, runner down/not down, player or ball inbounds/out of bounds, clock adjustments). "
This would fall under "touchdown/no touchdown", runner down/not down", and "player or ball inbounds/out of bounds" at the minimum. It was certainly reviewable.
