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
