Sorry but your email is very confusing.

What patch do you want us to apply? What does it fix exactly, and what does it not fix?

No, we should just fix it so that it works, not put it under the carpet.

In all cases I would highly recommend against XDMCP which is very
unsecure, unless you have done everything needed on your network. GDM is
able to start X sessions over SSH, which doesn’t have these problems.
