Well, there hasn't been a lot of work done on the subject but you probably
should look at
Now if you're seriously asking how one would do it, the basic approach taken
in the paper was to create a monad H that was a controlled subset of IO &
that did all the fundamental interactions with the the hardware.  The
operations of H, as with IO, have to be primitives in the runtime that
you're using and probably written in C or assembly.
