[linux-dvb] hybrid DViCO FusionHDTV5 Lite: dvb-bt8xx + lgdt330x + dvb-pll

I have been trying to enable support for DViCO FusionHDTV 5 Lite into 
dvb-bt8xx, using lgdt330x and dvb-pll.  I am pretty sure that I have 
done everything correctly, but I dont have a working 
"lgdt330x_set_ts_param" although I dont think I need one, as the bttv 
has no mpeg chip.  Am I wrong about this?  If so, how can I write this 
function?

Analog functions are working on this board already without a flaw.  The 
video4linux portion of this code can be found in video4linux cvs, bttv 
card 0x87 (135).  However, with dvb, I am getting an error (see all the 
way down below), and the frontend driver does not get detected.  I am 
sure that I have the i2c address correct, and I got my gpio values from 
playing with both regspy and btspy.  Any ideas?

Anyhow, here is my dmesg, first without DVB support enabled in 
bttv-cards.c, and then with DVB support (.has_dvb = 1,) and dvb-bt8xx.  
The file attached is the patch that I made against dvb-kernel cvs.
