It's really quite a big task to write a new driver. It takes an average of 2-3 months to fully write and debug.
There used to be an SNP driver that was part of the project. It was a user submitted driver. After version 3.5, when the architecture was changed, it no longer complied and I was no longer to get in touch with the original developer, so I had to remove it from the solution.
You can try to use one the older versions that still had the driver as part of the solution:
