If you still have a MediaForte/Typhoon/whatever SF16-FMR radio card and you want to use it with Linux, you can use this kernel driver. Be warned that I wrote this when I hardly knew how to program in C, you could say it's quite risky to have a kernel driver as "my first C project". Oh well, don't think it can be that much of a security risk since in the end I didn't really write this, I just copied code from a userspace program to kernelspace. If you're interested in that userspace program, you can find it here.
If you run Linux 2.6, it looks like there's already a driver for this card available in this kernel.
