Not that it really matters, but the current consensus is that corn-based ethanol production has about a 15% energy gain - that is, if you put in six units of petroleum energy in and you get about seven units out. Considering the amount of cropland and fertilizer needed, your conclusion that it is not a solution is 100% correct. The only biofuel that shows real promise would be an algae based biodiesel, and that's totally in the theory stage right now.
