If linux allowed any person to type setuid(0) in their programs and
actually get root, linux wouldn't be very secure, would it. setuid(0)
only gets you root if your program started with it in some way, either
by the setuid bit on the binary or running the program as root.
Can't really help you with your problem, but I can't wait till
capabilites when I can give myself CAP_RAW_IO (or some such)
and have everything work.
Use the setuid bit or run as root.

It was this kind of thinking that caused the problem in the first place.
