Well, since time was short I didn't want to hack the kernel. What I ended up doing was setting up an itimer for 10ms intervals and then measuring how much longer than 10ms I was asleep for. While this only collects samples at 100Hz, it will work with the default kernel.
Thanks for the suggestions,
Chris
