David,

Here I got something interesting.

1. Fresh booted machine and the dmesg is not showing any DVB info
2. Result of /sbin/lsmod command is below
3. Executed "/sbin/modprobe cx88_dvb"
4. dmesg now show som interesting output, see below at the end. And I get:

[root at HTPC ~]# ls -al /dev/dvb/adapter0/
total 0
drwxr-xr-x  2 root root    120 Dec 21 12:26 .
drwxr-xr-x  3 root root     60 Dec 21 12:26 ..
crw-rw----  1 root root 212, 4 Dec 21 12:26 demux0
crw-rw----  1 root root 212, 5 Dec 21 12:26 dvr0
crw-rw----  1 root root 212, 3 Dec 21 12:26 frontend0
crw-rw----  1 root root 212, 7 Dec 21 12:26 net0
[root at HTPC ~]#

Now, how can I make persistent? I mean so the module 'cx88_dvb' is
loaded every time.

The output from the steps (with some clips):
