Writing a driver is not the easiest way to go and if you don't know C then you can't write the driver. I think what your getting at (IIRC from your original post) is that you are asking someone to volunteer to write it for you. This is not a small request as writing kernel drivers is not a trivial task, can be very time consuming, and most people don't have time. Anyway, this looks like a pretty cool project and hopefully someone with some extra time on their hands will take up the task. Alternatively, you could learn C, learn how to write FreeBSD device drivers by reading the source code of existing drivers, and then write it yourself. :) I'm sure folks on this list (including myself) would be willing to answer any questions you had.
