 No change.
 
 But actually, the netbsd10 -12 (with or without your patch) runs
 smoother, even with firefox playing youtube videos, than netbsd-9.4,
 since I actually saw a relevant error message and chmod 666'd
 /dev/dri/card0. So I might be tempted to upgrade this laptop to -10 
 and run it that way (that is, -12).
 
 I see the following differences:
 
 9.4_STABLE:

 netbsd 10.1_STABLE with your patch:

 without your patch, same.
