    if (radeon_cs_space_remaining(pScrn) > (nBox * 3 * vtx_count + 5)) {
            loops = 1;
            nBox_loop = nBox;
    } else {
            loops = nBox;
            nBox_loop = 1;
    }

    for (i = 0; i < loops; i++) {
        ...

        while (nBox_loop--) {
            ...

Does this mean that nBox_loop will be zero when the for-loop executes for the
*second* time? Which means that the while-loop isn't going to stop again until
it wraps that 32 bit integer round.
