yeah, but even the recent mercurial with the patch should work with
2.6.12 was meant.

Yes, that fixes the V4L2_TUNER_DIGITAL_TV mode for the 300i beside the
problems with the IR chip and that now the first register of the tda9887
is fully reprogrammed and not only bit 7 of port2.

Take care and remember the problems with the tda8290 auto detection
code. It scans on the same address range than the tda9887 uses and with
this card the chip detection goes wrong ...

Until Hartmut provides the fix he is thinking about, you have to
modprobe -r saa7134-dvb/saa7134, tda9887 and tuner. Then modprobe
tda9887 at first!

Yes, might be, but I think it was quite tricky even for Gerd to get the
card running, some i2c quirks in saa7134-i2c are reminders ...

Seems it causes more work for Hartmut now and he might even fork out
with a extra mercurial version for the card for a while to have proper
testing, stay tuned :)

Cheers,
Hermann
