I thought it was because folic acid supports terrorism, Osama Bin Laden, communism, atheism, divorce, contraception, and butsecks.

Ugh, I hate vegemite.

Then you are unpatriotic and have allowed the anti-Australian terrorists to win.

No, that's DVD piracy. Watch any DVD and you'll see.

I have never ever heard of Vegemite.

Just go hang around in Australia, and eventually someone will hand you a Vegemite sandwich.

It's like, a law or something.

Dammit, suddenly I have Men At Work's "A Land Down Under" blaring in my head! 

EDIT: Quoted from wikipedia: "In October 2006, the Melbourne Herald Sun reported that vegemite is banned in the USA, with Customs officials going so far as to even search Australians for Vegemite when they enter the country. However, no official statement from the Food and Drug Administration or any other US government agency has been made specifically banning yeast extract products. Some believe that this is a misunderstanding."

Can anyone back this up?

Can someone explain what the problem is with folic acid in something other than bread/cereal?

in other words i have no idea

Folic acid can mask the signs of B-12 deficiency, which can cause severe nerve damage (among other things.)  I can see why they did what they did, but it seems a little paranoid to me...

Vegemite is the one of the world's best sources of Vitamin B (Including B-12 IIRC), so that's a somewhat flawed argument.
