[linux-dvb] Is my card supported/known? 1461:4836

Hi,

my new notebook is equipped with a DVB-T card, and I fear there may be
no support for it on Linux, yet.
The notebook (ASUS A7CC-7S018C) was released about a month ago, and I
guess the hardware is about the same age. Therefore, I'm not really that
surprised at not finding any information about the card on the Internet
(well, it would be kinda nice if AverMedia mentioned it on one of its
websites, but they don't seem to consider that necessary).
Windows Vista calls the card "AVerMedia M10D MiniPCI Hybrid DVBT".

lspci says this:

01:02.0 Multimedia controller: Philips Semiconductors SAA7133/SAA7135

        Subsystem: Avermedia Technologies Inc Unknown device 4836

PME(D0-,D1-,D2-,D3hot-,D3cold-)
                Status: D0 PME-Enable- DSel=0 DScale=0 PME-

And that's about all the information I got. I don't want to open the
laptop unless it's really necessary, so I've never actually seen the card.
I read that SAA7133 was supported quite well, so I tried to load the
right modules, but I *think* it didn't work (actually I have no idea).
People said I could use tvtime to check, but that doesn't work with my
video card. Anyway, I wanna use mplayer. But I don't know exactly how to
play TV with mplayer, so the reason I saw nothing but a black screen may
alsa have been me making a mistake when invoking mplayer.

Here's what I tried:
mplayer tv:// -tv
driver=v4l2:norm=PAL:input=0:amode=1:width=384:height=288:outfmt=yuy2:device=/dev/video0:chanlist=europe-west:channel=E2
(got it from Gentoo Wiki, didn't have time to read the mplayer manual, yet)

So, if anyone could tell me how best to find out whether card and tuner
are working (so I can try out all AverMedia cards or so), that would be
nice.

Here's what dmesg had to say:

saa7130/34: v4l2 driver version 0.2.14 loaded

So, my questions now are: Is the card known in any way? If not, how can
I best test the different existing drivers? If I don't find anything
there, are there some simple things I could change in the kernel
sources, or will I have to build a completely new driver? (as you might
notice, I'm not prepared to give up, no matter what it takes)

Ah, also: will it be _really_ useful to open the laptop and take a look
at the card?

TIA,
