3D accelrering i Mandrake 10

Jeg har installeret mandrake 10 på min laptop med et Ati radeon m6 grafikkort. Når jeg vælger den driver som passer til kortet spørges der om jeg vil aktivere 3d accelrering. Jeg svarer ja, men når jeg genstarter X er der stadig ingen 3d accelrering (200 fps i glxgears). Hvad kan der være galt?
