Iain,

      (1)  you need to get cx88_dvb to load instead of cx88_blackbird.
      (2)  you need the correct device nodes, ie various directories under 
/dev/dvb/adapter0 not a single device /dev/dvb.

      I found the following:

To do (1)....
   First check you have the correct module available to load by doing
modprobe -r cx88_blackbird
modprobe cx88_dvb
lsmod

You should now see cx88_dvb listed.   If you can't modprobe cx88_dvb you 
haven't compiled the correct patches / kernel options.

To make this happen automatically at boot I had to manually comment out all 
references to cx88_blackbird in
    /lib/modules/<your kernel dir>/modules.alias
and  /lib/modules/<your kernel dir>/modules.pcimap

It is something to do with the two modules having the same device code. 
Someone may have a cleaner solution but this does at least seem to work.

To do (2)...
You must update udev to version 050.
From: download.fedora.redhat.com 
/pub/fedora/linux/core/development/i386/Fedora/RPMS/

Download:  udev-050-1.i386.rpm

rpm -Uvh udev-050-1.i386.rpm





After reboot you should be up and running:-

You should see cx88_dvb listed in lsmod

You should see

    /dev/dvb/adapter0/demux0

    /dev/dvb/adapter0/dvr0

    /dev/dvb/adapter0/frontend0

    /dev/dvb/adapter0/net0

(Udev reports an error about microcode on startup but it seems to be 
irrelevant.)



HTH.   Let me know if you need furhter details on Kernel compile, etc.
