I have the Hauppaugue WinFast 2000 XP Nova-T card with the Thomson tuner.
bttv: driver version 0.9.15 loaded
bttv: snapshot date 2005-04-04
bttv: using 8 buffers with 2080k (520 pages) each for capture
cx2388x dvb driver version 0.0.4 loaded

cx88[0]/2: cx2388x based dvb card
DVB: registering new adapter (cx88[0]).
DVB: registering frontend 0 (Hauppauge Nova-T DVB-T)...

I tried 2.6.12-rc2-mm3 which seemed to have everything needed for this 
card, bit I get a segfault on insertion of the cx8802 module. I don't 
know if this is an indication of some hardware problem or if it's due to 
  some differences between Gerd's snapshots and what Andrew has in his 
-mm tree, but I have it all working using + Gerd's cvs-snapshot 
20050403. It also worked with some snapshots from 2.6.10 upwards. It 
would be nice to have it all under Andrew's tree for moving into Linus'.
