Only way White Sox let Buerhle leave is if St. Louis offers him crazy contract. So, it's possible, but I don't think Buerhle is gone.
Floyd being traded, IMO, is more possible. He's been inconsistent, you can get that out of Axelrod, Stewart or even Petricka.
The question is what value can we get for Floyd? I'm not sure anyone is going to give up much for him.
