 Combining the following two suggestions results in working but
 nonaccelerated Xfce4 on the Shuttle SG45H7 system with Intel G45
 Eaglelake graphics.  I am just relieved to be able to use a current
 kernel instead of an older one in any sort of working X.org Xfce4
 system.

 The complete procedure for me, after mv-ing the original intel_drv.so
 to save it and dropping the alternative intel_drv.so into
 /usr/X11R7/lib/modules/drivers, was to run
 # Xorg -configure
 which complained that no screens could be found but at least generated
 a xorg.conf.new, to edit xorg.conf.new to uncomment
 
 Option "NoAccel" "True"
 
 and finally to copy xorg.org.new to /etc/X11/xorg.conf
 
 I notice /var/log/Xorg.0.log now shows repeated calls to try and open
 the drm minor device.  Are the plans to have NetBSD implement this drm
 minor functionality or to just have one device at presumably
 /dev/dri/card0?
