I'm happy to be proven wrong. Here's what's written in line 488 of
encoder/encoder.c of x264 sources:

    if( !h->param.b_cabac )
        h->param.analyse.i_trellis = 0;
    h->param.analyse.i_trellis = x264_clip3( h->param.analyse.i_trellis, 0, 2 );

Now, I'd like to know if trellis _can't_ be implemented without cabac
or it's just that x264 folks just didn't care to implement that.
