Unknown CX23885 device

Hey Linux-DVB people

I'm trying to make an as-of-yet unsupported CX23885 device work in Linux.

I've tested that the device is not supported using the newest snapshot
of the DVB drivers. They did support a bunch of extra devices compared
to the standard ubuntu driver, but to no avail.

This is what I know about the device:

### physical description ###

The device is a small mini-PCIe device currently installed in my
Thinkpad T61p notebook. It did not originate there, but I managed to fit 
it in.

It has an "Avermedia" logo on top, but no other discernable markings.
I've tried removing the chip cover, but I can't see any other major chips
than the cx23885. I can take a second look, if I know what to look for.

I've tried several different card=X settings for "modprobe cx23885", and 
a few of them result in creation of /dev/dvb devices, but none of them 
really seem towork.

What can I try for a next step?
