Tevion DVB-T stick

Having followed the instructions for a similar DVB-T-USB stick here: https://www.dealextreme.com/forums/Default.dx/sku.8325~threadid.278942 I have successfully installed model WS-DVBTM2 on my PC: ASUS eeePC901 running Ubuntu remix 9.04.

It works consistently with Kaffeine every time I boot .

The problem is, that I have to manually load the modules, ie
sudo insmod dvb-core.ko
sudo insmod dvb-usb.ko
sudo insmod ec100.ko
sudo insmod mxl5005s.ko
sudo insmod dvb-usb-ec168.ko

I have tried to make the modules load by adding the names to /etc/modules, but it doesn't work.
When I check with modprobe (after booting with the complete modules file), 3 modules show as 'module already loaded'
the ec100 module loads, and the dvb-usb-ec168 module displays 'invalid character included'

I am puzzled because I have tried it several times now. Note: I have copied and pasted - not typed - the module names into the module file to avoid the error messages to no avail.

Any clues to what is going on here would be much appreciated.
