Ok.
The problem was the following :

In 2.6.17 :

  <M> Video For Linux                                                           
      &#9474; &#9474;
  &#9474; &#9474;               [*]   Enable Video For Linux API 1 (DEPRECATED) 
                                    &#9474; &#9474;
  &#9474; &#9474;               ---   Enable Video For Linux API 1 compatible
Layer

if you set  Enable Video For Linux API 1 compatible Layer (It should be a good
idea a first glance because the other one is DEPRECATED), you can not select:
 <M> Philips SAA7113/4/5 video decoders (OBSOLETED)

I'm recompiling a kernel and a new driver to test but it should be ok.
Thanks a lot
