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
cx2388x: snapshot date 2005-04-04
cx88[0]: subsystem: 0070:9002, board: Hauppauge Nova-T DVB-T 
[card=18,autodetected]
cx88[0]: hauppauge eeprom: model=90002, tuner=76
cx88[0]: registered IR remote control
ACPI: PCI Interrupt Link [APC3] enabled at IRQ 18
ACPI: PCI interrupt 0000:01:08.2[A] -> GSI 18 (level, high) -> IRQ 18
cx88[0]/2: found at 0000:01:08.2, rev: 5, irq: 18, latency: 32, mmio: 
0xe5000000
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 2.6.11.7 + 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'.
Regards
Sid.
