Here are some high-res pictures of both sides of the card. Scanned at
600dpi (300dpi the tracks were very close). Good idea to scan it by the
way, I like that, much better result than with a digital camera.

ok:
- The Atmel chip is an AT24C02 EEPROM. Does one of the 878As have a PCI
subsystem ID?
No, I don't see any PCI id's for the of the 878A's (relevant bit of
lspci -vnn below)
- The 74HCT04 is used to drive the clock from the oscillator to the
878As.
- The 74HCT245 is a bus driver for four pins of the connector CN3.
- The unlabled chip is probably a CPLD/FGPA. It filters the PCI REQ#
lines from the 878As and has access to the GNT# and INT# lines,
as well as to the GPIOs you mentioned. The bypass caps have a layout
that fits to the Lattice ispMACH 4A.
Ah, ok, so this is something to do with interfacing to the PCI bus?
- There is no mux or gate between the BNC connectors and the 878As.
The BNCs are on MUX0. MUX1 is connected to the two unpopulated 2x5
Headers.
So the UNKNOWN/GENERIC card entry should have the BNC connectors on its
first V4L input.
Have you tried passing pll=35,35,35,35 as module parameter?
I've just had a go at this, modprobe bttv pll=35,35,35,35, and using the
composite0 input in xawtv (first in the list) and still no joy. I just
get the same timeout errors repeating in dmesg:
[63204.009013] bttv: 3: timeout: drop=0 irq=46/26548, risc=3085d000,
bits: HSYNC OFLOW
[63204.513013] bttv: 3: timeout: drop=0 irq=84/26618, risc=3085d000,
bits: HSYNC OFLOW
[63205.016045] bttv: 3: timeout: drop=0 irq=121/26689, risc=3085d000,
bits: HSYNC OFLOW
[63205.519013] bttv: 3: timeout: drop=0 irq=158/26759, risc=3085d000,
bits: HSYNC OFLOW
[63206.021022] bttv: 3: timeout: drop=0 irq=196/26829, risc=3085d000,
bits: HSYNC OFLOW
I went through and tried each of the /dev/video[0-4] inputs in turn in
the hope that one of them had been initialized, but just got the
timeouts on them all.
I also went back and had another go with modprobe bttv
card=133,132,133,133, trying the "132" in each position and testing each
of the video devices (/dev/video[0-4]) as well in the hope that one
input got initialized, but no luck there either.
Any more ideas?
I can probably try the card in a Windows machine at the weekend if that
will provide any helpful information, however I don't have a driver CD
for it, so it may depend on me finding some drivers....
Thanks,
Rob.
