I would submit it if everything works (as far as you know). I would however explain in the notes alongside the module download that you cannot provide support.
I have suggested in the past that modules should be categorised based on whether or not the developer is able to provide support. As long as I know *in advance* that I need to fix any issues myself, I don't have a problem with unsupported modules.
I'm afraid I don't know the procedure for submitting a module. It should be in the FAQ?
