Well, maybe you where more right than me...

>From em28xx-dvb.c

	case EM2880_BOARD_TERRATEC_HYBRID_XS:
	case EM2881_BOARD_PINNACLE_HYBRID_PRO:
		dvb->frontend = dvb_attach(zl10353_attach,
					   &em28xx_zl10353_xc3028_no_i2c_gate,
					   &dev->i2c_adap);
		if (dvb->frontend == NULL) {
			/* This board could have either a zl10353 or a mt352.
			   If the chip id isn't for zl10353, try mt352 */
			dvb->frontend = dvb_attach(mt352_attach,
						   &terratec_xs_mt352_cfg,
						   &dev->i2c_adap);
		}
