Hi,
Here is my problem :

I try to set up a Nova-T 9002 (new model)
[cx22702 / cx 23882 / dtt 7592]

I built a 2.6.15.1 kernel without patches.

Here are some commands output:

debian-dvbt:~# uname -a

--------------------------------------------------

I do have feeling that everything is correctly
detected, i am quite suprised of the lsmod output
that looks empty (even if I do 'manual' modprobe),
any advice ?
(may be did I broke something in debian packages...)

I read a lot of things on this problem and tried many
solutions...without success. (built-in drivers,
modules, etc...)

What utils would you recommend to use to detect/load 
drivers ? (udev,hotplug)

In /dev/adapater0, one can see that there is no
video entry, could this non-presence affect the
tuning part ?

Thanks for your attention ;o)
