I try on last sunday to compile a new kernel (the last one : 2.6.20) with a blank repository on v4l-dvb archive and make the changes on it : it sucks !!! - the new kernel 2.6.20 does not recognized my board - when I try to compile new repository and install the modules, the saa7134 module doesn't want to load - when I search in files saa7134-dvb.c and saa-7134-cards.c the references to tuner_config, It was impossible to find them So, my questions : - how is it possible for me to compile last kernel 2.6.20 with third party v4l-dvb archives ? - when can I get this 2.6.20 working archives ? - what modifications can I perform to test and make working my board (1043:4871 reference)...
