Have you created the /dev/dvb entries.. ? If you are using udev, you 
need to create a udev script... Somebody could possibly help you out on 
that, as i don't use udev..

If you are happy with the stock drivers, use them else recompile the 
kernel with the latest drivers.. The reason being the driver got through

For documentation take a look at linuxtv.org, the top level 
documentation link points directly to the docs in CVS.
