Yes ... but why would you NOT use some form of physical dampening, in order to increase the gyros' sensitivity ? It's a bit like NOT using an elastic type basket to hold a studio microphone on it's stand, but instead, rolling off the bottom end in software after you've recorded all the low frequency bumps eminating from the floor via the mic stand.
How much assembler code are we talking about with Kalman filtering ? How complex is it ?
