It gets even more complicated if you need to support 1.2 kernels, which
those of us who are providing drivers for the Real World have to do....

This is what I do to make the Comtrol driver work under 1.2.x and
1.3.recent kernels. I don't think it works on pre-1.3.39 kernels;
supporting that would probably add even more complexity!
