Cancelling Rotation on a limited number of Axis

I've been attempting to develop a script that will do this for physical objects, like vehicles, but not necessarily as it might be interesting for some other things. Anyway, my problem is this: I'm having trouble figuring out just how to go about doing this. I know that llRotLookAt with ZERO_ROTATION does this quite nicely except it cancels ALL rotation and restores equilibrium to the object. So basically what I want to figure out is just what I should be doing to cancel rotation/restore rotation to global default (or some other prespecified rotation) on one or two axis while -not- canceling or modifying it on another.

Im not *exactly* sure if this is the solution you're looking for, but have you tried disabling STATUS_ROTATE_X, STATUS_ROTATE_Y, and/or STATUS_ROTATE_Z?

// Turns physical rotation on y axis off.
llSetStatus(STATUS_ROTATE_Y, FALSE);

Thank you, that seemed to be exactly what I was looking for. I am dismayed, though, that I spent a considerable amount of time considering the complexities of quaternions.
