3Dfx Banshee

This card has absolutly NO problems, and works flawlessly with an Arcade monitor. The changes to the driver, tdfxfb.c, is only to remove a couple of checks it imposes on the horizontal resolution: 
  //  var->xres = (var->xres + 15) & ~15; /* could sometimes be 8 */
  lpitch = var->xres * ((var->bits_per_pixel + 7)>>3);

  /*
    if (var->xres < 320 || var->xres > 2048) {
    DPRINTK("width not supported: %u\n", var->xres);
    return -EINVAL;
    }

    if (var->yres < 200 || var->yres > 2048) {
    DPRINTK("height not supported: %u\n", var->yres);
    return -EINVAL;
    }
  */

Green is below 4MHz, red above 19MHz.
