College Savings Plans

I turn to my vast and knowledgeable ...uh.... you guys.

My lady's kid is 7 and I want to start up some sort of College Savings for him so that by the time college comes around a good chunk of it can at least be paid for.

Does anyone out there know of any good plans out there for this type of investment?
Should I just open a 2nd savings account and stock pile the money in there until college comes around?

I figure a few of you out there had a few happy accidents whom you believe will one day head off to college to better their education and take care of you while you enjoy playing poker in your retirements and whatnot so that I could get some sort of advice.

Thanks a bunch
