Nothing, except that it hasn't been completely ported to all
architectures of NetBSD.
I've ported Ted's driver to NetBSD/i386 (and HP-UX...), though it
wound up being severely rototilled in the process..
In order to implement it correctly, you need:
- code to read a high-resolution timer
- code to hook into device driver interrupts and sample that
Both of these are quite machine-dependant, and I'm not in a position
to implement or test these for anything other than the i386 (and the
hp700..). Knowing *which* interrupts to hook is also an interesting
