Hmm, now that I look at it again from the profile angle, it does look clearly more like Cho's nose than Eric's... Funny, I've always looked at him from the front and thought that it's obviously Eric's; from the front, it seems much too wide to be Cho's nose to me. Eric has some pretty epic nostrils, they take up, like, half his face in witdth. Now I'm actually wondering if it's possible that Dirk got some sort of a mixture of the two noses... Trying to compare pictures, it seems that Dirk's nose isn't actually as wide as Eric's but still wider than Cho's. Or maybe I'm imagining it.

Either way, he's clearly got a Nose!
