    As stated, the kernel headers have nothing to do with user space code.

    But I'll educate you a little more.

    First, high resolution timers are not in 2.6.18. The hrtimers are, but
    the actual meat that makes them high resolution wont be in until
    (hopefully) 2.6.20 (or perhaps a little later).

    To use the high resolution timers (when they are in), you don't need to
    do anything special. nanosleep, and all the posix timers will get them
    automatically.
