First of all let someone verify if the foll, is correct b4 you proceed, there may be an easier way!!

Ok! look at this,

the module to be loaded is,
VIDEO_SAA7134_DVB and VIDEO_SAA7134 which depends on the foll, modules
VIDEO_DEV && VIDEO_SAA7134 && DVB_CORE . So you have to enable loading of the above as modules, in your kernel
Become root, Install ubuntu sources from apt/synaptic
#cd /usr/src/linux
#make menuconfig
1. This fires up a menu structure similar to the screenie, now navigate to the same structure as given in the shot, you can also search for the module name by selecting [/] key and typing the module name (case sensitive).
2. [select] to go into an item [exit] to come out of it [help] to read it's help text. 3. Press M to each of the above modules to enable them as modules.
4. Exit out to the top level and select [exit]. Press [ok] save the configuration.
Now do the following
# make install && make modules_install
This will take time. After it finishes,there would be a kernel "bzimage" created, copy this to /boot partition.
# cp /usr/src/linux/arch/i386/boot/bzImage /boot/<name of your previous kernel image> ( to ease out grub configuration, substitute the value by taking a look at /boot directory to sustitute the name of the kernel) press [y] if you are asked to replace the file?
close all progs, and reboot the system
Now the
new kernel boots-up
Issue the following commands as root,
# modprobe VIDEO_SAA7134_DVB
# modprobe VIDEO_SAA7134
The other dependent modules will be automatically loaded. Check if the card works, if it does we can then add the modules to be loaded automatically Good Luck!!
