You should isolate these out before looking any further. For AGP, make sure that 'device agp' is not in your kernel or loaded as a module, and for DRM make sure that your X config file omits the DRI/DRM options. If it still fails then it's almost certainly an X bug and not a FreeBSD bug. If it's a DRM problem then you'll still want to contact the X folks since that code is maintained outside of the FreeBSD project. If it's an AGP problem then we'll mark is as something that needs fixing for 6.1. Scott
