No me va la aceleración por hadware en kernel 2.6

He actualizado la versión del kernel de la 2.2.24 a la 2.6.3.9 y resulta que no me funciona la aceleración por hadware, en cambio con el kernel 2.2 si.
Mi tarjeta es una Ati 9600XT, he instalado los drivers y he activado la aceleración por hadware. Os copio lo que me sale al hacer glxinfo, haber si sabeis cual puede ser el motivo de que no funcione.
