me either. When I used the dvb-tools (I think that's what they were 
called... I'm getting forgetful with all this!) It installed the 
following in modprobe.conf:
(note that these are only 3 lines. 2nd line is long)

alias char-major-81 cx88-blackbird
install cx88-atsc /sbin/modprobe cx8800;/sbin/modprobe --ignore-install 
install cx88-dvb /sbin/modprobe cx8800;/sbin/modprobe --ignore-install 
cx88-dvb
install btcx-risc /sbin/modprobe tuner;/sbin/modprobe --ignore-install 
btcx-risc

I'm lost as to whether I need to have the alias char-major81 in there or 
not.

Very confusing.

opps.. that's a typo. I DO use:

/sbin/modprobe cx88-dvb
