Can you upload high resolution pictures of both sides of the card
somewhere? Something where we can follow the tracks to these chips.
Scanning the card with 300dpi should be enough.
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.

1x 35.46895M Crystal
Few cards use an 8x PAL Fsc crystal. Most have an NTSC crystal
(28.6363 MHz) and rely on the PLL for PAL. Maybe this helps to rule
out some card numbers.
I did have a look down the cardlist for ones with PLL_35 (?), but it
didn't help me. I dont think there are any with 4 inputs. Assuming
thats the right thing to do.
Hmm, quick followup, I've just been looking at the images more closely
and the top two (on the image) 878A chips appear to have tracks coming
out of the GPIO pins.
Top chip has a "few" from pins 56 to 61 (GPIO23-18) that look to go via
the 74HCT245 to the connector on the end of the card (not sure what
thats for though...)
2nd from top chip appears to have a "lot" of it's GPIO pins connected
up, pins 56-61 and pins 67 to 82 so GPIO 4 - GPIO 23. Which possibly
come up and connect to the unmarked chip...
Doesn't get me any further in making the card work, but hopefully it
helps you guys a bit :-)
I've tried Kodicom driver again
(http://linuxtv.org/wiki/index.php/Kodicom_4400R) with the "master card"
id=132 in all possible positions - 1st, 2nd, 3rd, 4th, but no success.
I still just get the bttv: 0: timeout: drop=0 irq=643/644,
risc=06470000, bits: VSYNC HSYNC errors in dmesg.
