You might have a look into the high resolution timer patches on top of
hrtimers at http://www.tglx.de/projects/hrtimers

The clockevents abstraction layer is a quick attempt to generalize the
problem around event generation. I'm stuck in some other work right now,
but I'm going to rework this layer soon. IMO John Stultz GTOD patches
and the generalization of clock events will be a sane base for high
resolution timers and dynamic ticks.
