 In -current it is enabled by default.
 
 NetBSD 5.1 (netbsd-5) is a different story because not all changes from 
-current
 are back ported so it may be not so stable if we enable it by default.
 
 For 5.1 you can load the kmod with /boot.cfg

 For the intel gfx chipset. For others it is not so much of an issue.
