Is this a rumor about saving seeds or is it not a rumor?

Yesterday, I heard someone talking about things passed by the Senate recently. One of the things she mentioned was that it is now "illegal" to save your own seed. She said that it was something that the Montsanto company had pushed through. Say what? If it is true, I'd really like to see people try to legislate this! And join the opposition. This is legislation gone overboard, if it is true!
