Try this (from dvb-driver):

        echo "Inserting DVB modules into kernel"
        # make sure input stuff is there for IR remote controls
        modprobe input
        modprobe evdev
        # vide4linux for av7110 based "full featured" cards
        modprobe videodev
        modprobe v4l1-compat
        modprobe v4l2-common
        modprobe video-buf
        # DVB core
        modprobe dvb-core
        # frontend drivers
        modprobe ves1x93
        modprobe alps_tdlb7
        modprobe alps_tdmb7
        modprobe stv0299
        modprobe ves1820
        modprobe tda1004x

        modprobe grundig_29504-491
        modprobe cx24110
        modprobe mt312
        # saa7146 based siemens/technotrend/hauppauge cards
        modprobe saa7146
        modprobe saa7146_vv
        modprobe ttpci-eeprom
        modprobe dvb-ttpci
        modprobe budget-core
        modprobe budget
        modprobe budget-ci
        modprobe budget-av
        # technisat skystar2
        modprobe skystar2.ko

# Create device nodes for the Linux DVB API with DVB_API_VERSION 2.
# The devices created are suitable for most current PC DVB cards,
# i.e. cards having one frontend, one demux and optionally one
# MPEG decoder.
# The script creates devices for four cards by default.

if [ -e /dev/.devfsd ]; then
        echo "It seems you are using devfs. Good!"
        exit 0

# get rid of old DVB API devices; do it twice for good measure...
