I've taken a photo of the board and a close-up of the only interesting chips
that I can see on it. Most stuff seems to be hidden in the big tin box.
here is a picture of the whole board:


And here is a close-up of the large microchips,
the smaller one that you can't read the writing on is the MT352:


The MT352 says on it: 
MT352 CG
0510F WS

Since I wrote my first message, i have tried modprobing the cx88 module with 
the card=19 option to tell it that the card is the Conexant Reference DVB-T 
design (hey, it might just work). After I do this, modprobing the cx88_dvb module 
gives me some more dmesg output than just  "cx2388x dvb driver version 0.0.4 
loaded". This is what it now shows:

cx2388x dvb driver version 0.0.4 loaded
ACPI: PCI Interrupt 0000:00:08.2[A] -> Link [LNKD] -> GSI 11 (level, low) -> 
IRQ 11
cx88[0]/2: found at 0000:00:08.2, rev: 5, irq: 11, latency: 32, mmio: 0xe4000000
cx88[0]/2: cx2388x based dvb card
mt352_read_register: readreg error (reg=127, ret==-121)
cx88[0]: frontend initialization failed
cx88-dvb: probe of 0000:00:08.2 failed with error -1

It seems it's now recognising it as a DVB card but failing when it tries to 
start controlling it :( . I think the help of driver developers may be needed 
for this one...
