Hi Daniel,
Mark D tried on this card back in November 2005.
We got it working so far, but Mark had on some channels only a bad
picture quality, not fully clear what caused it. Also radio is
unconfirmed/untested/unknown.
The card still needs an entry.
For what we found so far you can try, after modprobe -r related modules,
modprobe tda9887 debug=2
modprobe saa7134 card=46 tuner=66
Card=46 uses a somewhat rude method to switch the tuner on.
It pulls all gpio pins high, see down in saa7134-cards.c.
Mark reported like others, based on Marcin Gozdalik's tries on the PAL
version, that what you see in his patch suggestion would be enough:

For what I can see Mark forgot to replace the card=46 tuner=54 with
tuner=66, _current_ mercurial name is TUNER_LG_TALN and to add a line
.tda9887_conf = TDA9887_PRESENT,
Else, already present at card=46, if the card has external analog audio
in, it should be LINE1 _or_ LINE2 for comp1 _and_ svideo I would expect.
As said radio is unclear and you also have to add the card name and a
new number for it in saa7134.h.
For testing on audio and saa7134-oss 32000Hz, 16bit stereo you need sox
something like
"sox -c 2 -s -w -r 32000 -t ossdsp /dev/dsp1 -t ossdsp -w -r
32000 /dev/dsp"
For external audio in, say on LINE2, you have to switch the saa7134-oss
mixer explicitly to that. Same goes for radio, if added. Maybe it is on
LINE1, like card 46 has it, but we don't know how much tda9887 like this
tuner really is.
If you try on saa7134-alsa you maybe can use something like
mencoder -v tv:// -tv
driver=v4l2:device=/dev/video0:width=640:height=480:chanlist=europe-
west:alsa:adevice=hw.1,0:audiorate=32000:amode=1:forceaudio:volume=95:immediatemode=0:norm=PAL -ovc lavc -lavcopts vcodec=mpeg4:vbitrate=3600 -vf pp=lb -oac mp3lame -lameopts cbr:br=128:mode=0 -o alsa-test.avi
adapted to your TV conditions and assuming a station is tuned.
Keep us informed how it goes. (real tuner should be ALPS TSEH1)
Good Luck,
Hermann
