Anybody can test the driver using my tree, as mentioned above. You may
not see why we need the tda9887 to be configured right now, but if you
REALLY need to be convinced, please google the following search phrase:
"gene heskett pchdtv tda9887" (read the entire thread)... Sure, the code
might work in today's kernel without the tda9887 being explicitly
programmed, however, in older kernels, or maybe in some future kernels,
the driver might break without this line.

None of that should be necessary. It sounds to me like you just need to
set up /etc/modprobe.conf
Obviously, you have multiple cards in your machine at once, and this is
mucking up your testing environment.
1) Simply doing:
should be enough to get analog television working. This will
automatically load tuner.ko and tda9887.ko (and others) as dependencies.
should be enough to get digital television working. This will
automatically load nxt200x.ko and dvb-pll.ko (and others) as dependencies.
You do not need to explicitly load the firmware -- it will be loaded as
I can only imagine the need for you to do that entire sequence above if
you want to see all the debug messages showing up at once in the log.

All you need to do is add "saa7134-dvb" to /etc/modprobe.conf
Please, humor me... Download *my* mercurial tree ( hg clone
http://linuxtv.org/hg/~mkrufky/atsc ) DO NOT alter any files.....
Follow the standard build instructions:
make install (as root)
edit your /etc/modprobe.conf (or is it /etc/modules.conf ? i forget) as
reboot your system.
When it comes back up, everything should just work, without the need to
do your strange sequence of module loading and unloading. If anybody
can confirm that this works out-of-the-box now, then I will have this
merged into master.
If, however, you find that you DO need to do this module
loading/unloading sequence, then I can deduct that you are having
GPIO-related troubles, and I will NOT have this merged into master until
those can be resolved.
Let me know...
