Are you planning to release the source for this driver? If you are, maybe it's a good idea to make the skeleton available. I at least wouldn't mind devoting some time to it, either by trying to figure out how it can work myself, or much better and more realistically, help you out if there are some testing / other tasks you know have to be done for the driver to work. I do have quite a lot of programming experience many years ago, but at least, at that time I did program hardware directly, since there weren't really any drivers, and the specifications came in a book.
So, I'd really like to hear what you think.
