ipw2915abg marche pas sous Linux

j'ai changé ma ipw2100B pour une ipw2915ABG. Alors sous windoze ça marche mais sous Linux (Fedora 6) pas du tout. Et comme d'hab. quelques listing  

[root@nemrod firebird]# dmesg | grep ipw

le firmware est dans /lib/firmware/ récupéré sur http://ipw2200.sourceforge.net/firmware.php version 3.0 mais j'ai essayé les versions antérieurs sans résultats.

[root@nemrod firebird]# ls -1 /lib/firmware

/lib/firmware/ipw2200-bss.fw

/lib/firmware/ipw2200-ibss.fw

/lib/firmware/ipw2200-sniffer.fw

le scan avec /sbin/iwlist eth1 scan me liste plein de point d'accès dont le mien donc je pense que point de vu détection ça marche.

j'ai shooté le firmware de l'ancienne ipw2100 qui marchait nickel sous Linux.
Merci de votre aide...
