This also happened with 2.6.{35,34} and IIRC .33 too. Its the same with TDA10021. I just saw it has been reported already [6] The kernel/udev doesn't even load the drivers automatically for some reason.. if CONFIG_DVB_TDA10023 has been build solid into the kernel while the rest has been built as module.
