Ok, here a better patch for dvb-bt8xx.c:

Me and a friend wrote some debugging code for the mt352.c:

we changed:
#define I2C_MT352_ADDR 0x0f
to
static int I2C_MT352_ADDR=0x0f;
and changed mt352_attach to:
static int mt352_attach (struct dvb_i2c_bus *i2c, void **data)
{
	/* important debug :) */
        for(I2C_MT352_ADDR=32;I2C_MT352_ADDR--;)
                printk("SADD=%x: %x\n",I2C_MT352_ADDR,mt352_read_register(i2c, 
0x7f));
	/**/

        if (mt352_read_register(i2c, 0x7f) == 0x13)
                return dvb_register_frontend(mt352_ioctl, i2c, NULL,
                                             &mt352_info);

        return -ENODEV;
}

it seems that the mt352 on my card doesn't react to any of this addresses.
output:
SADD=XX: 0
i2c_adapter i2c-2: sendbytes: error - bailout.
mt352_read_register: readreg error (ret == -14)

for XX=1f downto 0

thanks to Daniel for his help.

cheers
