I don't use udev, so can't help you much with that .. But should not be 
difficult..

Something that i use to run in verbose and debug mode ... to load the modules

/sbin/modprobe dvb_core dvb_shutdown_timeout=0 dvbdev_debug=1 
dvb_frontend_debug=1
/sbin/modprobe video-buf
/sbin/modprobe bttv i2c_hw=1 card=0x71 bttv_verbose=1 bttv_debug=1
/sbin/modprobe bt878 bt878_verbose=1 bt878_debug=1
/sbin/modprobe dst dst_verbose=1 dst_debug=1
/sbin/modprobe dst_ca dst_ca_verbose=1 dst_ca_debug=1 session=0
/sbin/modprobe dvb-bt8xx debug=1

You don't have to give type_flags ... It is no longer used ...
It is detected by the driver ..

Yes, that should not happen.. For the card the frontend driver is dst itself..
I have been working on it with 2.6.9 and the CVS as of 16th Dec...

Don't know whether anything has broken up recently regarding the new frontend

What model is your card anyway ?
