>Description:
This is connected with xsrc/42262.

As Jeremy stated I should open a new bug.

I used the patch ( http://netbsd.org/~jmorse/drm4.diff ), that is mentioned in 
xsrc/42262 and managed to run Xorg with DRI. But every program I open, that 
wants to use DRI fails with:

$ glxgears
Failed to initialize GEM.  Falling back to classic.
Segmentation fault (core dumped)

Program terminated with signal 11, Segmentation fault.

Even glxinfo fails with same problem.
