Ok, after a lot of research I've finally understand what is causing  
the problem. It's the resolution that the kernel tries to set that is  
not accepted by my TV. It seems to accept only 720x480 and 720P. I've  
found that after running X I can change to a virtual terminal  
(console) but not before. That must be because X sets the resolution  
to an valid one.

I must then try to find how to make one of the 2 valid resolution  
default by the kernel.

Thanks,
