dmesg gives the follow output for /dev/video0 (UNKNOWN/GENERIC sounds like
improper id as you suggest):

bttv: Bt8xx card found (0).
GSI 29 sharing vector 0xEA and IRQ 29
ACPI: PCI Interrupt 0000:07:01.0[A] -> GSI 36 (level, low) -> IRQ 234
bttv0: Bt878 (rev 17) at 0000:07:01.0, irq: 234, latency: 132, mmio: 0xd8000000
bttv0: using:  *** UNKNOWN/GENERIC ***  [card=0,autodetected]
