I'm using two cards in a box (using a passive riser card).  I'm seeing
the following logging:

And lspci reports:

00:14.2 Multimedia controller: Conexant: Unknown device 8802 (rev 05)

The relevant portion of my /etc/modprobe.conf file looks like:

# DVB stuff
alias char-major-81 cx88-dvb
alias char-major-81-0 cx8800
alias char-major-81-1 bttv
options dvb_core dvb_shutdown_timeout=0
options bttv i2c_hw=1 card=0x71
install bt878 /sbin/modprobe --ignore-install bt878
install dst /sbin/modprobe --ignore-install dst
install dvb_bt8xx /sbin/modprobe --ignore-install dvb_bt8xx
install cx88-atsc /sbin/modprobe cx8800;/sbin/modprobe --ignore-install 
install cx88-dvb /sbin/modprobe cx8800;/sbin/modprobe --ignore-install 
install btcx-risc /sbin/modprobe tuner;/sbin/modprobe --ignore-install 

What am I overlooking?  I'm not seeing the second
frontend device being registered...
