Hmmm... did you test that with the current driver (i.e. the one in
2.6.16)?  If I read the code correctly, the card option may get the
bttv driver running, but the dvb driver would fail with the message:

  bt878_probe: card id=[0x0], Unknown card.
  Exiting..


Btw, why does the system lock up?  IRQ storms?  Could setting
no_gpioirq for BTTV_BOARD_UNKNOWN avoid the lock up[1]?

Ciao, ET.


[1] In older bttv versions even with no_gpioirq set, gpio irqs
were enable for a short moment and may have caused irq storms.
But that was fixed some months ago.
