I'm punting on this for now. I'm afraid of violating assumptions about how the clock behind this interface works (and we do very specific stuff like calculating CPU clock speed), so I don't want to try to replace it. We'll revisit when we need to do serious profiling on ARM; we'll definitely notice that this functionality is missing when we try to use it.
