It seems that the most current linux-image-2.6.32-24-generic image (amd64, v2.6.32-24.42) is broken again completely. I tried with v4l-dvb-20100130, v4l-dvb-20100517 and without any custom modules and was not able to get any signal anymore.
The previous version 2.6.32-24.41 worked at least with v4l-dvb-20100130
