Short answer. Grab the *_dri.so's out of the linux binary distribution of XFree86-4.1.0. There shouldn't have been major changes to prevent this from working with the MGA. Okay, here's the deal with the linux emulation prblems for the compiled _linux_ libs for the CVS resident stuff... in xc/programs/Xserver/hw/xfree86/os-support/linux/drm/xf86drm.c there are several calls to drmOpenMinor() that need to be wrappped with a #if defined(XFree86Server) fd = drmOpenMinor(i, 1); #else fd = drmOpenMinor(i, 0); #endif If that function is called with the create flag set the *_dri.so's never fall back to just trying to open the /dev/dri/card? devices by name, ignoring the major number on the device node (which is different between freebsd and linux for the dri device).
