Nope it won't cause any problems, none of the XF[86][68]_FBDev servers where accelerated for matrox, other libs (SDL etc) that have accel for matroxfb don't work correctly for ppc either. Changing the endian to little is the *right* thing, big-endian mode doesn't offer us anything beyond problems in matroxfb 8/16 bit accesses become a nightmare there... Kostas
