Some advice on "teaching" my son guitar?

I would have put this in the Musicians Corner section, but I want opinions from anyone with teaching experience or advice. Here's some background:
I picked up the guitar at 14, took lessons for a year, didn't ever do what the teacher wanted, and ended up quitting lessons because I thought the teacher was moving too slow. As a result, my guitar playing is sloppier than it should be, I can't read to save my life, and 24 years later, I rarely pick up the guitar anymore, though I still am passionate about the instrument. I get frustrated because I can't play what I hear in my head, but can't stand practicing. I dug myself in a hole because I lacked patience and discipline.
My son is 10 and has always been interested in my guitars, so we bought him a guitar and amp this last Christmas. I haven't showed him much of anything really, because I didn't want to pressure him into playing. I just kind of wanted him to noodle around with it and get comfortable. However, right off the bat he started playing single-string Metallica riffs, getting the notes right, and even tuning the guitar to, as he says, "the notes I hear in my head."
I have tried to show him chords and things to give him some more tools to work with, but he really doesn't seem that interested. He'd rather just fiddle around. Now I am torn. The kid obviously has an ear for music and an urge to play, and I want to encourage that as much as possible. I don't want him to end up like me, sloppy and uneducated. However, if I push him to "learn," I am afraid I will either turn him off, or end up taking this creativity he has and tainting it by forcing structure on it. He has far more natural music ability than I ever had, and I really, really don't want to see it go to waste.
Should I try and force a little structure on him? Or should I just let him keep noodling away? My heart is leaning toward letting him just do it on his own, but at the same time, I would hate for him to get frustrated like me because he does not have the knowledge to play what he hears in his head.
I would appreciate any and all opinions on the matter.
