Hi, The new RPMs for XFree86 4.0.1 are missing all the DRI drivers in /usr/X11R6/lib/modules/dri thus causing 3D hardware acceleration to fail. All the other modules appear to be correct, this is the only missing set. John P.S. I solved my immediate problem by grabbing the binary versions from XFree86, they're in Xmod.tgz for those who need them.
