  First of all I have to say that I have to inspect the changes Jesse had
included related to pipes and planes. These could be significant.

  Menwhile, I've found this piece of code at i830_lvds_mode_fixup function
in i830_lvds.c:

    if (intel_crtc->pipe == 0) {
        xf86DrvMsg(pScrn->scrnIndex, X_ERROR,
                   "Can't support LVDS on pipe A\n");
        return FALSE;
    }

  Does this actually apply to all the cards or is there any exception?

  Thanks.
