Many aren't documented, but section 4 of the manpages is the place
where they are suppose to be documented... if you look at netintro(4),
you'll see a few for network devices..
A few others like agp(4), bpf(4) and meteor(4) have ioctl's described...
For the others, often the definitions in the header file is usually
enough, as they sometimes also contains comments describing them...
