 I have a Thinkpad SL300 with the same problem (and I guess same graphics
 hardware). I just tried the http://netbsd.org/~jmorse/drm4.diff and at
 least Xorg starts with DRI enabled and without leaving an unusable display
 behind.
 
 But it's not over yet, because every application, that try to use DRI is
 getting an Segfault:
 
 $ glxgears
 Failed to initialize GEM.  Falling back to classic.
 Segmentation fault (core dumped)
 
 Core was generated by `glxgears'.
 Program terminated with signal 11, Segmentation fault.
