also a good read on the new HRT implementation -
http://lwn.net/Articles/152363/

still need that hires clock source somewhere - but being tied to the ktimer
api ought to make it easier to use many variants of ppc,x86,x86_64, many of
which have high resolution clock sources that look unlike HPET....

Ktimers work in-kernel and are available in userspace via the posix hires
timers....
