http://www.linuxcnc.org/docs/2.5/html/drivers/hostmot2.html#_pins_3 stepgen has a pin velocity-fb compare velocity feedback to the commanded velocity, that gets you spindle at speed. connect your spindle display to velocity-fb, that gets you a ramped display. While it is still open loop, it's reasonable to expect the spindle motor is at the RPM the stepgen says it is. You may need to adjust the units on the commanded and stepgens velocity-fb. May be other little details but you get the idea.
