Burdz - You evidently made the wheel on the turn, right?

If so, I think you have to put your opponent on either a wheel (same as you), a six-high straight (in which case you also split the pot), or both a wheel and a six-high straight (in which case you get quartered).

The prudent play is to check/call the river because the distinct possibility of your opponent having both a wheel and a six-high-straight is greater than the possibility your opponent, even if seemingly clueless, was jamming with nothing after the turn.
