I can't see why that doesn't work for you - A copy and paste of it works 
OK for me.

You don't really need the filters for default classes and it's best to 
delete the root qdisc before you add a new one.

Maybe you still had some filters around from an earlier test that 
messesd things up.

I am using the latest TC, iptables and 2.6.12-rc1.
