If you are using microstepping drives, then you may be able to use
steppermod rather than freqmod. Steppermod is able to crank out
a lot more step pulses/second than freqmod, but the timing is rougher.
If the stepper drive smooths these out, then you will have no problem.

Another way to fight this is to use my (not ready to release yet)
stepper rate generator. I will be demo-ing a prototype of this at
NAMES this month.
