@Passel: I changed the looping condition as you suggested, it still runs at CPU dependent speed. I would have to ask at the DOSBox forums whether DOSBox supports vertical retrace.

Wait....Before you do that, run a game called Prince of Persia on DOSBox and change the CPU speed and see if the game runs faster or slower. Prince of Persia was the first DOS game I had ever seen that ran at the same speed regardless of how fast or slow the processor was. Even Alley Cat ran at different speeds depending on processors. I played both games extensively in my childhood. Prince of Persia ALWAYS ran at the same speed. If it can do that in DOSBox, then what you're asking is possible. You just have to figure out how they did it.
