VDR can't tune on 3.5 kernel

Hello
I know it isn't probably supported but it doesn't hurt to ask.
I use the newest kernel 3.5 with some experimental driver for pctv452e.
Using szap I can tune channels, I can save them using cat, I can analyze 
them using ffmpeg.
Hovewer I can't use VDR because it says like below:
