Background: There are 2 modules with a similar purpose.
Your kernel tree has a tveeprom module file, normally at 
/lib/modules/'uname -r'/kernel/drivers/media/video/
The tuner modules for the cx88 dvb stuff are under there in (naturally) 
/cx88
Elsewhere there is a tveeprom-ivtv module. The 'where' seems to depend 
heavily on the distro. If that line is not commented out of 
modprobe.conf, then all calls to tveeprom are re-routed to tveeprom-ivtv.
But the HD3000 drivers will not work with the tveeprom-ivtv module. The 
Hauppauge pvr cards will, however, work with the tveeprom module.

If you have a PVR500 card and want to use it, you NEED ivtv.
But you do have problems with your modprobe.conf

Add the following line (which always existed in my setup.)
alias char-major-81 videodev

The section above is otherwise correct. I suspect that the extra line 
above, and the missing char-major-81 videodev are the source of your 
problem.

How old are the downloaded files you are using for this setup? You 
should not need to use cx88-atsc.

I think this line is missing a '-r ': should be /sbin/modprobe -r cx8800

As noted elsewhere, since the kernel loads these modules as soon as it 
finds the HD3000 hardware, it may (will) get the order wrong and will 
load the wrong module. Modprobe.conf does not seem to unload the wrong 
and load the correct modules.

Try removing these lines from your modprobe (comment out) and then run 
in a console:
rmmod cx88-blackbird
rmmod cx8800
rmmod cx88-dvb
modprobe cx88-dvb

Check dmesg and look for /dev/dvb/adapter0/dvr0 to be created.
If so, then add these lines to /etc/rc.local. rc.local is the last 
script file run during boot and before the graphical console is started, 
so its a good spot to put debugging and install scripts.

I have no idea what this is for. I thought the btcx stuff was for the 
old bt chipset cards...
