How about d.extract directly in GRASS (available in latest CVS):

I have no idea about this, but display speed is an important issue for
me as well. Glynn has implement monitor-less rendering which seems to be
faster than the current rendering via monitors (see
following). I hope that this and some profiling of d.vect might allow us
to speed up diplay significantly.
